List of bugged equipment

This list aims to catalogue equipment which does not function as would be expected based on its tooltip, or that has other problems - or missing information - in its description, function, or location. This list is unlikely to be comprehensive as it is likely there are many issues with items of which we are unaware.

As this list deals with problems that have a high likelihood of being changed in patches and hotfixes, it is likely that entries will be incorrect following an update.

All entries are currently correct as of Hotfix 29.

Amulets

Item	Bugs
Amulet of Bhaal	First Blood is non-functional in Honour mode.
Amulet of the Devout	The additional Channel Divinity Charge granted by Godswill restores on a Short rest contrary to the text. However if the extra charge is expended, and then the amulet is unequipped, the extra charge will not reappear if the amulet is re-equipped before a Long rest, and at this point cannot be restored with a Short rest.
Amulet of the Drunkard	The healing effect from Booze Remedy works only once, on the first turn of the inebriation duration.
Fireheart	The fire damage from the Heat status applied by Fervent Flames will retrigger Fervent Flames, which will then reapply the Heat status.
Sentient Amulet (Very Rare)	Although the tooltip says the Shatter spell granted by this amulet is level 2, this upgraded version actually deals 4d8Thunder damage, in line with the level 3 version of Shatter.
Spell Savant Amulet	Spell Amplification can grant an extra spell slot once per character per long rest, despite the Spell Slot Depleted condition on the item.

Armour

Armour	Bugs
Armour of Moonbasking	Lunar Bestial Fortitude states it provides a +1d4 bonus to Armour Class, but it is actually a flat +2 bonus.
Elven Chain	This item does not have a Proficiency Group (in order for all classes to be 'proficient' with it). As a result, items such as Bracers of Defence, Bonespike Boots, and Corellon's Grace that are not supposed to give their bonuses while wearing armour still provide their benefits with the Elven Chain equipped. The extra movement speed granted to monks by Unarmoured Movement is also not lost when wearing this armour. The  Defence fighting style can grant up to +2 AC when used with this armour. For the same reason as above, Defence does not normally work with the Elven Chain as it is not properly considered armour. To work around this, the armour has a hidden passive that grants +1 AC if the wearer has Defence. But if the wearer also has another piece of armour equipped (e.g. a helmet), the normal +1 AC from Defence will also be applied for a total of +2 AC.
Flawed Helldusk Armour	The required saving throw for Lesser Infernal Retribution is attributed in the combat log to the wearer of the armour, rather than the attacker, but is correctly rolled by the attacker. Though Lesser Infernal Retribution states an attacker must be within 2m, it actually only triggers on a melee attack.
Helldusk Armour	This item does not have a Proficiency Group (in order for all classes to be 'proficient' with it). As a result, items such as Bracers of Defence, Bonespike Boots, and Corellon's Grace that are not supposed to give their bonuses while wearing armour still provide their benefits with the Helldusk Armour equipped. The extra movement speed granted to monks by Unarmoured Movement is also not lost when wearing this armour. The  Defence fighting style can grant up to +2 AC when used with this armour. For the same reason as above, Defence does not normally work with the Helldusk Armour as it is not properly considered armour. To work around this, the armour has a hidden passive that grants +1 AC if the wearer has Defence. But if the wearer also has another piece of armour equipped (e.g. a helmet), the normal +1 AC from Defence will also be applied for a total of +2 AC.
Shadeclinger Armour	Shadeclinger grants the  Clinging Shadows condition, which is not removed when taking off the armour. This can be exploited to get this condition applied to an entire party by having each character equip and then remove the armor one by one.

Cloaks

Item	Bugs
Cindermoth Cloak	Despite the tooltip stating that an attacker receives  Burning, Flaming Shroud requires a DC 12  Dexterity saving throw before Burning will be applied. The required saving throw is attributed to the wearer of the cloak, rather than the attacker. Though Flaming Shroud states an attacker must be within 2m, it actually only triggers on a melee attack.
Cloak of Elemental Absorption	Due to a coding error, the passive Absorb Elements will only function once per Long Rest.
Cloak of the Weave	This items lacks the necessary passives in the game code to allow Absorb Elements to function properly.
The Deathstalker Mantle	There is a bug involving this item with the Illithid power  Cull the Weak. If the equipping character has the passive feature activated and kills a target, the effect won't activate (or immediately gets cancelled).
Wavemother's Cloak	The description on Water Layer Protection incorrectly uses the same description as  Wet, despite the two conditions having different effects.

Clothing

Item	Bugs
Bloodguzzler Garb	Grievous Retribution states that it grants 1 turn of Wrath, but it actually grants 2 turns of the condition.
Cloth Armour	Grievous Retribution states that it grants 1 turn of Wrath, but it actually grants 2 turns of the condition.
Enraging Heart Garb	Ruintamer Heart has no effect, and does not function in-game.
Garb of the Land and Sky	Breezeswift Speed is only removed when making a weapon attack, as opposed to the next attack roll.

Footwear

Item	Bugs
Boots of Speed	Due to a scripting error, Click Heels applies the disadvantage on opportunity attacks to the wearer.
Boots of Stormy Clamour	Due to a hidden condition that gets applied when a ranged weapon attack misses, Arcane Echomalefaction will apply even though it appears it should not.

Handwear

Item	Bugs
Gloves of Baneful Striking	Baneful Strike applies a 1d4 penalty to all Saving Throws for its duration, not just the wearer's next spell.
Gloves of Battlemage's Power	Battlemage's Power is nonfunctional.
Gloves of Belligerent Skies	Though stated "upon the target(s)", Thunderous Conversion can only trigger once per attack. This means that AoE spells (e.g.  Radiance of the Dawn or  Flame Strike) can only apply  Reverberation to the first target in the log order, leaving the rest without the effect. This also means that dealing multiple instances of damage in a single attack (e.g. with  Lightning Arrow) will still only apply 2 turns of  Reverberation.
Gloves of Crushing	Crushing Blows applies its attack roll bonus twice.
Helldusk Gloves	Infernal Acuity grants the wearer +1 all attack rolls.
Ichorous Gloves	Despite the description stating it affects targets, Ichorous Corrosion only applies once per turn and thus only affects one target.
Jhannyl's Gloves	Due to a coding error, it is possible for Defy Villainy to trigger in combat before it actually has a noticeable gameplay effect, and with the Long Rest cooldown it will not trigger again.
Legacy of the Masters	The +2 bonus to attack rolls granted by Arming Enhancement also affects spell attacks, unarmed attacks, and throw attacks; however, except for throw attacks involving weapons with the Thrown property, those attacks do not receive the +2 damage.
Spellmight Gloves	Spellmight will add its damage bonus to any melee weapon attack that counts as a spell (all smite spells except Divine Smite) yet not apply the -5 to hit penalty.
Swordmaster Gloves	Sword Mastery does not increase the damage of off-hand melee attacks.
The Reviving Hands	Aegis Palms will not apply Death Ward when casting Revivify on an already dead ally. Casting it on an ally who is downed, but not yet dead, will apply Death Ward.
Wondrous Gloves	When equipped to a Bard that has exhausted all Bardic Inspiration points, Troubadour's Wonder will grant a new point. This effectively allows for infinite Bardic Inspiration points from un-equipping and re-equipping the gloves after spending said points.

Headwear

Item	Bugs
Bonespike Helmet	Fury in the Marrow will have its psychic damage totally nullified on a successful Wisdom save instead of halved.
Cap of Wrath	Last Stand only applies 1 turn of Wrath.
Coldbrim Hat	Due to a hidden condition that gets applied when a ranged weapon attack misses, Coldbrim Chill will apply even though it appears it should not.
Dark Justiciar Helm	Swathed in Shadow passively adds its Saving Throw bonus at all times, not just when attacked.
Diadem of Arcane Synergy	Due to a hidden condition that gets applied when a ranged weapon attack misses, Synergetic Moments will apply even though it appears it should not.
Helldusk Helmet	Infernal Sight does not see through magical darkness; it only grants immunity to  Blinded and does not provide the cone of light that could otherwise be aqcuired by obtaining the Darkvision effect from a different source, such as a spell or from having the passive innately via race.
Helm of Balduran	Stun Immunity does NOT protect against  Stunning Gaze (as cast by the Bhaal cultists) but does protect against  Mind Blast,  Stunning Strike (Melee) and  Stunning Strike (Unarmed).
Marksmanship Hat	Marksmanship only applies to ranged weapons in the main hand, thus Hand Crossbows equipped in the off-hand are unaffected.
Pyroquickness Hat	When triggering Fiery Return with a Bonus action (for example with  Metamagic: Quickened Spell), the extra bonus action will be consumed immediately.
Shapeshifter Hat	The additional Wild Shape Charge granted by Nature's Embrace restores on a Short rest contrary to the text. However if the extra charge is expended, and then the helmet is unequipped, the extra charge will not reappear if the helmet is re-equipped before a Long rest, and at this point cannot be restored with a Short rest.
Steelwatcher Helmet	Artificial Sight does not provide the cone of light that could otherwise be acquired by obtaining the Darkvision effect from a different source, such as a spell or from having the passive innately via race.

Musical Instruments

Item	Bugs
None known so far

Rings

Item	Bugs
After Death Do Us Part	Shadow Possession is removed instantly from the wearer upon leaving the downed state.
Callous Glow Ring	Callous Glow does not specify the damage type, but it is Radiant.
Coruscation Ring	Arcane Radiance inflicts  Radiating Orb regardless of the wearer's light level.
Ring of Absolute Force	Absolute's Tempest will function even if the wearer is not branded.
Ring of Feywild Sparks	The bonus to Spell Save DC is not indicated by the in-game tooltip.
Ring of Spiteful Thunder	Spiteful Thunder triggers on any damage, not just Thunder. The saving throw is hidden and not shown in the combat log.
Sunwalker's Gift	Sunwalker's Gift does not provide the cone of light that could otherwise be acquired by obtaining the Darkvision effect from a different source, such as a spell or from having the passive innately via race

Shields

Item	Bugs
Ironvine Shield	Ironvine activates on any attack, not just melee attacks.

Weapons

Weapon	Bugs
Artificial Leech (+1)	None of the weapon actions provided by this weapon are actually availiable to the player when the weapon is equipped. When wielded by any nurse this weapon deals an additional 1d6 Necrotic damage. A coding error causes a misplaced '1d6' to appear in the weapon's list of properties.
Bonesaw (+1)	None of the weapon actions provided by this weapon are actually availiable to the player when the weapon is equipped. When wielded by any nurse this weapon deals an additional 1d6 Necrotic damage. A coding error causes a misplaced '1d6' to appear in the weapon's list of properties.
Charge-Bound Warhammer	If this weapon is bound by an Eldritch Knight or Pact of the Blade Warlock, the weapon will retain its Favoured Weapon passive until the next long rest even if the character binds another weapon. The weapon will even retain this passive if the weapon is used by another character, different from the one who bound it. If this weapon is bound by an Eldritch Knight or Pact of the Blade Warlock, this weapon will permanently retain the lightning damage bonus from Shocking Bound even if the character binds another weapon. The weapon will even retain this passive if the weapon is used by another character, different from the one who bound it.
Cruel Sting	When this sword is first looted from Kar'niss it is listed as dealing an additional 1d6 Psychic damage, however this is due to a bug that causes the weapon to retain the Spindleweb Fanaticism (Granting 1d6 Psychic damage to him and his allies) effect from Kar'niss. This extra damage is removed if the player completes a Long Rest with the weapon in their inventory. Dropping the weapon on the ground or stashing it in a container prior to each long rest will allow it to retain Spindleweb Fanaticism indefinitely. The effect is also overwritten by Elemental Weapon if applied.
Dolor Amarus	Dolor Amarus does not deal an additional 7 damage on unarmed attack critical hits (includes Throw attacks).
Duke Ravengard's Longsword	The temporary hit points granted by Stirring Execution are actually based on the Charisma modifier of the character receiving them, not the character holding the sword. The minimum of 1 still applies.
Everburn Blade	Sometimes the visual burning effect will stop functioning. Dropping the weapon, picking it up, and then re-equipping it fixes the issue. The burning effect is not visible in cutscenes.
Exterminator's Axe	Scourge of Pests states it provides additional damage to Insects. This is incorrect, and it provides additional damage to Myconids instead.
Hellfire Greataxe	This weapon has a hidden condition MAG_FIRE_DIPPED_HELLFIRE which is supposed to make its 1d6Fire damage ignore fire resistance. Additionally, Hellflame Cleave and the Hellfire surface it creates are also both supposed to ignore fire resistance. Neither of these effects are currently ignoring fire resistance.
Hellrider Longbow	Fiendish Fire is applied by any damaging effect made by the wielder, including spell casts and melee attacks. Attacks and spells that affect multiple creatures apply the effect to all of them, rolling a separate saving throw for each.
Justiciar's Scimitar	Shadow-Blinding is non-functional in Honour mode. This weapon has a hidden version of the Shadow Blade (passive feature) applied to it, which does not function because Shadow Blade is nonfunctional.
King's Knife	In the game files, the root template of this sword (UUID 5908898d-5d9e-40de-ab07-3f8fb5f0174c) actually describes a shortsword, which is also used as the basis for the Knife of the Undermountain King. In fact, the magical properties of the Knife of the Undermountain King are also added to this root template (via the tag), meaning that this item should have those properties as well, and will do so if spawned via the console. However, the weapon that's actually spawned in-game is not directly based on the root template, but rather on a stat entry called WPN_KingsKnife which in turn inherits properties from the WPN_Longsword stat entry. This ends up making this item functionally identical to a common longsword.
Knife of the Undermountain King	The Shadow Blade (passive feature) granted by this weapon does not grant advantage against obscured targets.
Lightning Jabber	Shocking Sting states that it has a chance to apply  Shocked, but the condition actually applied is the similar but less potent  Shocking Grasp. Despite being labelled as a Spear, the Lightning Jabber is actually tagged in the game files as a Javelin and as such does not work with the Polearm Master feat.
Monster Slayer Glaive	Monsterslayer also adds 1d4 to attack rolls in addition to the damage rolls listed. This passive also applies to ranged attacks while this weapon is equipped, adding 1d4 to attack and damage for them. Spells cast while this weapon is equipped will gain 1d4 to their attack roll, but their damage is not increased.
Moonlantern	The Moonlantern containing Dolly Dolly Dolly still produces a stationary Moonshield Aura when dropped on the ground even after she has been freed from it.
Mourning Frost	The  Ray of Frost cantrip granted by this weapon uses the Spellcasting Ability Modifier of the party member from when it is first equipped. This modifier remains locked for that character and is not affected by respec or subsequent multiclassing.
Pelorsun Blade	Undead Bane provides Advantage to all attack rolls against Undead.
Phalar Aluve	The 1d4 Thunder damage does not trigger effects requiring Thunder damage on items such as Hat of Storm Scion's Power or Gloves of Belligerent Skies regardless of whether the character triggering the damage has the items or is the character activating Phalar Aluve: Shriek; Reverberation will not apply. This is because the thunder damage dealt to the enemy is from a passive effect placed on the enemy, rather than originating from the attacker which is necessary to trigger such items. This effect is changed in Honour difficulty, and functions as expected.
Rat Bat	It is not listed anywhere in-game, but the Rat Bat deals an extra 1d6PiercingDRS damage against any target.
Ritual Axe	The Scourge Mistress' Bane always inflicts  Bane on hit.
Shadow Blade (weapon)	The Shadow Blade (passive feature) granted by this weapon does not grant advantage against obscured targets.
Shining Staver-of-Skulls	Casting  Light on this weapon will overwrite the innate Light passive, causing it to end.
Sorrow	The attack roll for the  Sorrowful Lash cantrip uses the Spellcasting Ability of the player character, and remains locked for them from the moment this weapon was first equipped. However, its damage uses their current Spellcaster Ability Modifier. Therefore, if a character respeccs without ever having changed to another weapon, this results in attacking with their old Spellcasting Ability while damaging with the modifier of their new one. To remedy this, Sorrow must be unequipped and re-equipped.
Staff of a Mumbling Wizard	Firebolt? does not increase in damage beyond 1d10Fire despite the tooltip stating that it does.
Staff of Arcane Blessing	The in-game description of the Mystra's Blessing effect is incorrect. See the article Mystra's Blessing for details. Mystra's Blessing is only applied when Bless is cast as a level 1 or level 2 spell.
Staff of the Ram	The Staff of the Ram knockback and stun effects apply to any attack made by the wielder of this item. This weapon appears in the game code as if it should deal an additional 1d6Force, which is not present on the item when acquired through normal in-game means.
Sussur Dagger	The item description states that it applies Silence on hit, but it actually requires a DC 12  Constitution saving throw.
Sussur Greatsword	The item description states that it applies Silence on hit, but it actually requires a DC 12  Constitution saving throw.
Sussur Sickle	The item description states that it applies Silence on hit, but it actually requires a DC 12  Constitution saving throw.
Sword of the Emperor	Shapeshifter Slayer also adds 1d4 to attack rolls in addition to the damage rolls listed. This passive also applies to ranged attacks while this weapon is equipped, adding 1d4 to attack and damage for them. Spells cast while this weapon is equipped will gain 1d4 to their attack roll, but their damage is not increased.
Syringe (+1)	None of the weapon actions provided by this weapon are actually availiable, if this weapon is equipped. When wielded by any nurse this weapon deals an additional 1d6 Necrotic damage. A coding error causes a misplaced '1d6' to appear in the weapon's list of properties.
The Baneful	If this weapon is bound by an Eldritch Knight or Pact of the Blade Warlock, the weapon will retain its Favoured Weapon passive until the next long rest even if the character binds another weapon. The weapon will even retain this passive if the weapon is used by another character, different from the one who bound it.
The Long Arm of the Gur	Revenant Scourge currently does not function due to the item missing a required hidden condition.
Trepan (+1)	None of the weapon actions provided by this weapon are actually availiable to the player when the weapon is equipped. When wielded by any nurse this weapon deals an additional 1d6 Necrotic damage. A coding error causes a misplaced '1d6' to appear in the weapon's list of properties.
Vicious Battleaxe	Dolor Amarus does not deal an additional 7 damage on unarmed attack critical hits (includes Throw attacks).
Vicious Shortbow	Dolor Amarus does not deal an additional 7 damage on unarmed attack critical hits (includes Throw attacks).
Voss' Silver Sword	Interplanar Slayer does not add the 1d4 bonus to attack rolls.
