How to Beat Grym

Use the Hammer In the Middle of the Adamantine Forge

Grym is a boss that appears when forging your first Adamantine gear. Grym is resistant to almost all forms of damage, but becomes vulnerable to damage when standing in lava. There is also a massive hammer in the center of the Adamantine Forge with Grym's name on it.

Preparation for Bringing Down the Hammer

Before you start the encounter by turning the lava wheel, have one character stand by beside the forge lever.

Position another character in the middle to act as bait, preferably one who has Magic Missile or a Scroll of Magic Missile so you won't whiff when taking Grym's aggro. Having Disengage is also helpful to prevent Grym from making an Opportunity Attack.

Magic Missile Effects

Lure Grym to the Center

Any character who attacks Grym will be designated as the Prime Target and chased down. Let your bait take aggro by casting Magic Missile or use a ranged attack on Grym. When Grym is right in the middle, get away from the hammer, using Disengage if available.

Pull the Forge Lever

Have your character standing by pull the forge lever to bring down the hammer and deal massive damage to Grym. This will knock Grym down, but the character who pulled the lever will now be the Prime Target.

You'll need to hit Grym with the hammer twice to beat it, so manage Grym's aggro and position your party accordingly to bring down the hammer again.

Beware of the Magma Mephits

After using the hammer, Magma Mephits will join the fight. Be careful as they explode on death and can disarm you with Heat Metal, so try to kill them off before they get close. If you have an Eldritch Knight in your party, you can use Weapon Bond beforehand.

The Magma Mephits will only spawn once, when you drop the hammer the first time. Subsequent hammer drops will not cause another wave to spawn.

Eldritch Knight Subclass Guide

Use Bludgeoning Damage While Superheated

Grym is virtually resistant to all forms of damage. Grym will only take damage when Superheated, and this happens when it has been standing on lava. When Superheated, Bludgeoning damage is most effective. If you can't manage to get Grym under the hammer, you'll have to slowly whittle away its HP.

Grym starts off Superheated, but will harden eventually when the lava recedes. Turn the lava wheel, the one you used to start the Grym encounter, to bring in more lava.

Grym Location

Found in the Adamantine Forge

Grym can be found in the Adamantine Forge in Grymforge, as soon as you turn the lava wheel. You'll need to fight Grym when forging your first Adamantine item. Don't worry as you won't need to fight Grym every time you forge an Adamantine item.
