Any good WindBreaker builds?

Storm Breath + Arrow Rain = fail, I'm pretty sure.

Push range seems to be .x not .range, so it's 300, not 150. At least, that's what I've discerned from the videos I've seen, though in that case, I have no idea what .range would mean. Correct me if I'm wrong, Isaac.

Well, in either case, one of the two is not defined as doing something, but it's either 300 push or monster position +150 which is complete fail for Arrow Rain.

The idea is to push mobs into a corner, then Rain the HELL out of them. Not Push, Rain, Push, Rain. You don't just push monsters away and spam an attack, you close the gap after pushing. Pushing isn't for distance, it's for mob stacking.
