This is a build I’m strongly considering for update 17. The goal of the build is to be able to switch back and forth between EE capable cc and dps roles simply by changing destinies (Magister vs Shiradi). The build sacrifices Toughness, GSPen and ESPen feats, which would probably make it nonviable without multiple past lives. It retains 50 spell pen and a 55 enchantment dc in Magister, and the first three tiers of Archmage enchantment and evocation SLAs (for fun with Shiradi). Any suggestions or help identifying glaring weaknesses would be welcome.
