Battlemage with the Staff of Corruption becomes absurdly fun on high levels. The only issue is survival without tough armor.
Camouflage is a decent match for the staff of corruption. I had transmutated a mage skill for the rogue’s “don’t wake enemies unless adjacent” skill on my corruption run and it was going pretty good with the monsters fighting each other while I explored and drank tea. I also had a wand of blast to yeet those who would get too close.
It’s been a while, but I remember it was a good fun run.
Yeah, that works together well. Also Elemental Blast with the Corruption (which makes all nearby enemies amok) is great for crowd control — sneak near, trigger, bail and let them fight among themselves.
I tried this with a wand of lightning. I got the staff to +12 before a succubus killed my mage. The wand’s limited to ranged targets, and my scale armor +2 only made the demons laugh.
