I tried to fight Maat last night. Lvl: 66. GAxe skill: 217. GAxe skill cap: 232
I eat Meat Mithkabob, and equipped extra +acc stuff at the expense of +STR/+atk.
Pre-WS melee: 2 out of 3 attacks connected, for roudly 280 dmg each.
First Raging Rush: 680 dmg.

Second Raging Rush: 281 dmg.

Fragmentation: 20 dmg.

Maat's HP left when I died: ~50%
I guess I better get my GAxe skill closer to cap before trying again.
