I think that Grym fight doesn't live up to player's expectations because of 2 things:

1.) An anvil plot-kill possibility that on one hand makes the boss too easy to beat, and on the other hand does not let you unleash the party abilities meticulously developed through the whole act.

2.) Damage immunity transiting into damage resistance. This once again makes you unable to unleash the party abilities meticulously developed through the whole act. The boss just doesn't care what mighty spell you've learned or a powerful item you've found. It doesn't care if you've made some creative and powerful party build. All it cares is getting clubbered to death.

What do you guys think of:
- Removing the plot kill or significantly weakening anvil's damage
- Increasing the Grym's HP while replacing natural immunity with natural resistance which would change to normal damage for some types upon superheating.

Let me know your opinion on that fight! smile
