Instead of a boomerang though, she has a single target nuke that stuns you (her Q)
Her W is like old Sivir's bouncing blade things, only its manaless.
Instead of a spell shield she has a flat AD increase.
Her ult, isntead of being an AoE AS+MS increase launches out a whole bunch of her Q's, randomly, to the nearest targets (can be on minions)
Oh, she's also Irish, rides a cat, and would spill your entrails if her Goddess demanded it =p http://www.dota2wiki.com/wiki/Luna
