Got the war hammer from caves as a +1 with a blazing enchantment. Had it as a corrupting war hammer in dwarf king and later got lucky with the vampiric enchantment! Last SoU used on arcana ring for them juicy vampire heals. Ring of arcana was originally a ring of haste+2 that i transmutated.
I think i never went under 100 hp during Yog fight as i was healing like crazy thanks to the RoA and vampiric enchantment combo. I had a spare RoH+1 at the time i went for the transmutate.
