Some of the loot in the grove is pretty good. I like Kagha's amulet that gives you an extra d6 poison damage after being healed. There's also the hidden glaive (I think it's called "Sorrow"?).
My Assassin/Gloom Stalker appreciates the shortbow that gives you an initative bonus.
Nere's boots are also damn good.
I need to try the forge again, I think I can do the fight if I really put my all into it.
Put the strongest hammers you have on 2 mele fighters with 2 attacks so you need to be level 5. He actually goes down fairly easy.
