List of bugged passives

This list aims to catalogue passives which do not function as would be expected based on their tooltips, or which have other problems - or missing information - in their description, function, or location. This list is unlikely to be comprehensive as it is likely there are many issues with passives 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.

Passives

Name	Bugs
Accursed Spectre (passive feature)	This feature has a once-per-long-rest limit set incorrectly in the game files. As a result, it can be used an unlimited number of times per rest.
Actor	The ability score increase can increase Charisma beyond the stated maximum of 20.
Adrenaline Rush	The in-game tooltip stating that Adrenaline Rush grants 2 turns of Wrath is incorrect, it actually grants 3 turns of the condition. The in-game tooltip states that Adrenaline Rush is once per turn. It is not.
Arcane Echomalefaction	Due to a hidden condition that gets applied when a ranged weapon attack misses, this passive effect will apply even though it appears it should not.
Aura of Murder	Enemies that are resistant or immune to Piercing damage will receive Piercing vulnerability while within the Aura of Murder (instead of having neither resistance nor vulnerability).
Coldbrim Chill	Due to a hidden condition that gets applied when a ranged weapon attack misses, this passive effect applies even though it appears it should not.
Companion's Bond	The in-game description says that the bonus scales with "your" (i.e. the Beast Master's) proficiency bonus, but in fact it uses the companion's proficiency bonus. This means the bonus will not increase to +4 until the final level 11 upgrade to your animal companion rather than at character level 9.
Damp Aegis	The description on Water Layer Protection incorrectly uses the same description as  Wet, despite the two conditions having different effects.
First Blood	Does not work on honor mode
Fury In The Marrow	As of Patch 7, hostile creatures making a successful Wisdom saving throw receive no damage instead of half damage.
Grievous Retribution	The in-game tooltip stating that the effect grants 1 turn of Wrath is incorrect, it actually grants 2 turns of the condition.
Heart of the Storm	Despite its tooltip stating otherwise, Heart of the Storm activates on cantrips.
Inevitable Resolve	Tasha's Hideous Laughter and Fear are not removed by this passive.
Infernal Acuity	The Infernal Acuity passive grants the wearer +1 all attack rolls.
Infernal Sight	Infernal Sight does not see through magical darkness; it only grants immunity to  Blinded and does not provide the cone of light that you would otherwise get by obtaining the Darkvision effect from a different source, such as from a spell or from having the passive innately through race.
Infernal Weapon	The roll for the  Poisoned saving throw is not shown in the combat log for either a successful or failed save. Because it has a low DC 12  Constitution saving throw, this can give the impression that the poison effect does not work at all.
Ironvine	Ironvine activates on any attack, not just melee attacks.
Lesser Infernal Retribution	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.
Mage Hand Legerdemain	If cast near a party member with See Invisibility, the mage hand may instantly be seen and lose invisibility. This only happens the moment it is cast; ungrouping and casting farther away from the See Invisibility party member will avoid this.
Magic Initiate: Cleric	This feat has an unlisted effect that increases the maximum AC bonus from Dexterity while wearing Medium Armour from +2 to +3. This effect is equivalent to the Medium Armour Master feat. Also like that feat, this effect will break the Exotic Material feature of certain Medium Armours.
Magic Initiate: Sorcerer	When provided by this feat,  Shield uses spell slots like an ordinary spell without a once-per-long-rest restriction. However this also means that it cannot be used at all by a character with no spell slots.
Magic Initiate: Wizard	When provided by this feat,  Shield uses spell slots like an ordinary spell without a once-per-long-rest restriction. However this also means that it cannot be used at all by a character with no spell slots.
Magical Ambush	Due to a coding error, Magical Ambush is removed instantly unless the character is hiding in a  Clear Area.
Metamagic: Twinned Spell	Due to the lack of a TargetRadius check for projectile spells, Twinned Spell is compatible with the ranged version of certain spells while also being incompatible with the melee version. An example of this is  Ensnaring Strike.
Monsterslayer	The Monsterslayer passive effect granted by this item 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.
Mystra's Blessing	The in-game description of this passive feature is incorrect, and actually should read:  Bless grants an additional 1d4 bonus to spell attack rolls. What really happens is that if a caster has this passive feature, creatures they cast Bless on gain two separate conditions: The regular Bless condition, granting a 1d4 bonus to all saving throws and attack rolls. The special Mystra's Blessing condition, which only grants another 1d4 to spell attack rolls. It's possible to lose the regular Bless condition (due to the caster losing concentration) while retaining the Mystra's Blessing condition. In this case, the creature will be left with a 1d4 bonus to spell attack rolls and no other bonus, despite the tooltip of the condition claiming otherwise.
Polearm Master: Bonus Attack	Despite not adding +10 bonus damage from  Great Weapon Master, it will add -5 from the attack roll if it's toggled.
Psionic Dominance	As of v4.1.1.4425968, this ability appears to be bugged. It works on Chain Lightning, a Level 6 spell, despite Proficiency Bonus being capped at 4.
Rebuke of the Mighty	The description of this passive states it requires a Dexterity saving throw. This is incorrect, as it requires a Strength saving throw.
Reliable Talent	For unknown reasons, Reliable Talent is known to fail under some circumstances. When rolling a religion check for the Mirror of Loss, the reliable talent fails to work for every other character or so. Also, when picking pockets while under the effect of Greater Invisibility, the Sleight of Hand check works fine, but the Stealth check may roll under 10 (both skills with expertise), though on a failed check the invisibility does not get dispelled. Whether the invisibility could get dispelled on a failed reliable talent roll is yet to be tested, so don't rely on this fact too much.
Revenant Scourge	The effects from this passive currently do not function.
Ruintamer Heart	Ruintamer Heart has no effect, and does not function in-game.
Rupturing	The in-game description says the target has a DC 13  Constitution saving throw to avoid the Ruptured effect. However, this is not true and the condition will always be applied. Following attacks don't stack Rupture turns. Enemies hit by it will reset for 3 turns again.
Scourge of Pests	The in-game tooltip for this passive says it grants bonus damage against insects, but instead it works against myconids.
Sculpt Spells	Despite being an AoE Evocation spell, this ability doesn't work with  Moonbeam.
Sentinel: Snare	Though this applies to druids in Wild Shape and does deal damage, the Damage Roll is empty/bugged as of Hotfix 19.
Shadow Blade	This effect does not function, and advantage is not granted against obscured targets.
Shadow-Blinding	In Honour mode, this feature is non-functional.
Shapeshifter Slayer	The Shapeshifter Slayer passive effect granted by this item 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.
Shar's Protection	Even though this passive feature is not listed in the Dark Justiciar Half-Plate (Rare), casting Shar's Aegis with the aforementioned item equipped will still apply  Sharran Retribution to the wearer.
Shield Bash	The description of this passive states it requires a Dexterity saving throw. This is incorrect, as it requires a Strength saving throw.
Shocking Sting	The in-game tooltip for this effect says it has chance to apply  Shocked, but the condition actually applied is the similar but less potent  Shocking Grasp.
Soul Catching	Soul Catching has numerous errors: It states it requires an "unarmed hit" while the  Grasp Essence condition states "hit a creature with an unarmed attack". Functionally, any damaging unarmed attack will trigger the effect, even against world items. It states the wielder regains 10hit points, but instead it grants an ability that when used provides the healing. It states the wielder may gain Advantage on Attack Rolls and Saving Throws until the end of their next turn, while the Grasp Essence condition states the wielder may gain Advantage on Attack Rolls or Saving Throws before the end of their next turn. Advantage is not actually gained, but rather an Interrupt is granted that provides the wielder with a choice of either adding a +5 bonus to a single attack roll or to a single saving throw, at which time the Grasp Essence condition is removed. Due to a coding error, Grasp Essence will be removed from the wielder if it takes damage and does not have any temporary HP.
Spellmight	The Spellmight passive 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.
Stirring Execution	The in-game description incorrectly states that the number of temporary hit points granted is equal to the Charisma modifier of the character who applied the condition. This is likely a bug.
Swathed in Shadow	Swathed in Shadow passively adds its Saving Throw bonus at all times, not just when attacked.
Synergetic Moments	Due to a hidden condition that gets applied when a ranged weapon attack misses, this passive effect will apply even though it appears it should not.
The Scourge Mistress' Bane	While the item description says 'chance,' the chance to inflict  Bane on hit is 100%.
Thunderous Conversion	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.
Tides of Chaos	Tides of Chaos as a passive toggle is currently (as of v4.1.1.6072089) bugged and does nothing; it is only usable as a reaction.[Needs Verification]
Titan Weapon	Titan Weapon always applies its bonus damage on ranged weapon attacks, not just when "it improves your chance to hit" (which it does not do).
Undead Bane	Despite the description, this passive provides Advantage to all attacks rolls made against Undead targets.
