Grym Bug?

[Ivan]

I banished Grym to give me time to get everyone in place, but he came back with immunity to ALL damage types. Not just resistances, but he gained to immunity to everything, including bludgeoning damage.

Is this a bug or is it normal?

Get him to walk in the lava. The lava removes his immunities

Never even met him. Man, my first playthrough missed so much.

[Pyromus]

He be default has immunity to all damage. Being in the lava softens the metal he's made of and drops it down to just (what I'm assuming is) the resistances you saw when he was banished.

[Hex]

He is always immune to everything unless he is overheating from walking in lava, that's the mechanic of the fight.

Oh thanks. I am glad I asked.
