Interesting info. Is this save file you posted in droids arent OP ? i played that game and got to 87 int with Depth of thought, and black hole spell was devastating for enemy troops
Question : did you use Ring of mind item for +3int on 30 battles ? And did you consider instead +1int belt to use Metamorphic axel for +4int from Tower in Darion island?
That would be truly terrifying spell dmg
