Well it stack, and it's also effected by duration. And the speed buff doesn't reset as long as you keeps stacking it (like how blood rush works). So you could get 100%+ speed for ~50s for ~100 energy with jack-of-all-trade build.

Though that eats a lot of slots... It's annoying to optimize for sure.
