Grym is a powerful Construct that eternally protects The Adamantine Forge. It cannot be damaged without becoming Superheated first.

About Grym

Grym is the eternal golem guardian of The Adamantine Forge hidden away in Grymforge. It is made of adamantine and defends the forge against any who might try to use it.

If the Adamantine Forge is used, Grym will activate and attempt to destroy its users.

Attacks and Abilities

Combat Tactics

Grym is immune to all types of damage and can send melee attackers Reeling. Its Adamantine Skin passive causes Grym to be unable to take damage until it has been Superheated by standing in lava. This will also remove its Intense Adamantine Backlash passive. Once superheated, Bludgeoning damage is most effective against Grym.

New Resistances when superheated:

Grym's Vengeful Guardian passive causes it to gain the condition Threat Assessment when attacked which will then mark the attacker with Prime Target. Grym will then chase and attack the creature, which can be utilised to lure the golem into lava - or even beneath the hammer of the The Adamantine Forge itself. Pulling the forge lever while Grym is standing on the central anvil, and is superheated, will hammer it for 2x

Bludgeoning

and knock it Prone. However, using the forge to damage Grym immediately removes Grym's Superheated condition and can even summon a group of Magma Mephits. Hammering Grym while not superheated will knock it prone but will do no damage and might still summon the Magma Mephits. Regardless of your approach, keep at least one party member by the lava valve, since the lava will recede after two turns, making the golem invincible again. Alternatively the lava valve can also be activated by shooting an arrow at it, or some familiars, such as Mage Hand, can also interact with the lava valve in place of a party member. Note, however, that using a familiar for the initial activation of the lava valve will bug the encounter and prevent Grym from spawning.

Before the fight it is wise to spread out your party, placing your casters in the back and melee up front near the gate where Grym will appear. Using elixirs such Elixir of Hill Giant Strength and Elixir of the Colossus will give a notable boost for your melee fighters. Before turning the valve, ensure all party members are standing on raised areas and enter Turn-Based Mode to prepare additional short duration buffs. It is almost a must to give one of your melee characters Haste for the extra attack and added AC. Applying weapon oils such as the Oil of Accuracy helps boost your Attack Rolls high enough to more easily beat Grym's high AC. Lastly, ensure you use weapons that deal Bludgeoning damage to exploit Grym's vulnerability.

Notes and Trivia

There is a Steam achievement (A Grym Fate) for defeating Grym without using the forge hammer. Despite its large amount of HP and high AC, proper preparation with Bludgeoning weapons on a Hastened Fighter and/or Barbarian can quickly wear it down.
As of Hotfix 6 there is no cooldown for the application of Superheated condition. Thus, it is possible to reapply the effect by activating the lava valve (has a slight delay, check Grym for status effects) and consequently hitting Grym with the hammer multiple times per turn. This can be easily achieved by placing a character within shooting distance of; both the lava valve and hammer lever and then shooting them both with arrows. For example a Hasted lvl 3 Thief / lvl 2 Fighter has essentially 5 actions when dual wielding hand crossbows, and can kill Grym in a single turn of combat at tactician difficulty. (Grym has to be first lured under the hammer with a second character, and Grym has to stand one leg in lava one under hammer)
