Damage Boost is annoying because it's really great but almost impossible to use (At this point.) Against a high level player without getting your ass beat in. I've experimented with some setups for it but not of them seem viable. One setup is after hitting them with lightning, use your damage boost, and teleport in. The problem is you can't block so you have to be extremely wary of wakeup attacks.
I'm not sure however, I actually am going to start messing with setups for it again here soon to see where it gets me. But as of now it doesn't seem viable. I'll post more if I figure out anything.
