[@rivaan] Interesting concept, but you may want to rethink your build a little.

More stats does not equal more damage, all the damage mainly comes in from skills. Sure it means you can do more feats relating to the stat, but what stats do is they're your maximum limit for skills. Although it'd be different if you did this knowing that already, since it'd properly reflect your character being a very frail girl with high magical prowess.

I'd just like to inquire on Broken Body, could you give me an example of how it'd work? Considering the explanation is a little unclear.

Calamity's Sneer should be more something along the lines of... "Upon dealing sufficient devastation in a surprise attack, her image becomes that of destructive terror and inspires fear in witnesses. Some may flee, and others may simply lose morale". Since you can do sufficient destruction without high level spells.

"Strike even the Gods", hmmmmmmm. I think you have the opportunity to do something cooler with this. Say in this dire circumstance, she gains access to a new set of spells to represent her Calamity Witch class? Since as is, it's kind of plain.

And Mental Purge will only activate once a battle, generally.
