(in response to the other comment, I thought that her W didn't reset AA timer ><)

"The triggering attack will apply other on-hit effects and can critically strike as normal. Asterism's relationship with dodge, parry, block and blind has yet to be tested. The bonus damage will not trigger on structures."

Dodge/Blind - Bonus damage will not apply, nor consume the buff. Parry - Bonus damage will be blocked, and consumes buff. Block - Bonus damage will apply, and consumes buff.

iirc; and i'm off to eat dinner now.
