Null Blade + Battle Mage + Ultima - 13/18 rounds

My mage game, detailed for every round.

Null Blade + Harold, the Hateful Hat is great combo for crits.

Ultima Ascension , when placed correctly, amplifies all Null damage.

All else is for survival / Amping Ultima's buff creation / Keeping the buffs from being stolen.

Any and all feedback is appreciated. :)
