Whats the skillset? Thats a lot of spell power, mana and mana regen.
Skillset is here
Golemancy, Promethean Magic, Magic training, Blood Magic, Ley Lines, Burglary, and Fungal Arts. Basically I tried to squeeze in as many mage classes while retaining the bare minimal utility requirement. I went with Golemancy over any other art because it packed the most utility into a single magic skillset as far as I could tell. The key point is the wall summon which solves three issues in one skill: Knockback, damage, and teleports. Obviously it doesn't teleport you, but it's more like teleporting walls between you and what you want to get away from.
Burglary could easily be replaced by any other similar skill, I just like having lockpicks. Archeology, the perception thing or even tinkerer would be good for dealing with traps but my problem with those is you need to invest points into them to really get much use out of them, which in turn I believe will lower your potential spell power.
So far pretty happy with it. Got a bit lucky with a +mana regen orb early on, which is why I've got so much now. I'm actually getting at least one mana point per turn on top of blood magic, and I end up killing stuff in mobs more often than not so I've basically got unlimited mana. I'm also packing 20 Night caps which is +22 instant mana each. Fungal arts basically covers any potion you could want for a mage without any of the crafting hassle. I'm going to try using this build in Rogue difficulty at some point, I think.
