Might wanna consider reducing the required distance travelled for maximum damage increase on R from 4000 to 2000.

I mean, to move 4000 units in 5 seconds; most people wouldn't even be able to do that even if they wanted to.

Or you could perhaps even keep the 4000, but make it so that Xia herself can also increase the damage. Make her work for that damage increase you know; nothing's ever free in life.
