How are you firing 760k mouth darts in a full-attack? I thought it was only 3 darts per attack, not all of them.
Also, what's the War Domain association do (and for), and why do I fear that my first question will be answered by this one?
Oh, and how are you getting Aptitude on each of the mouth darts so you can actually apply Boomerang/Chakram Ricochet to the darts?
