This has been hard to me to duplicate, but it has happened more than once, and even caused so much confusion that it led to a win in Walatiki.
I was too low level to do any sort of damage or tanking in practice battlegrounds, so I went with annoyance. Flash Bomb, Grapple, Kick, Leap, etc. Aside from running around spamming Flash Bomb and Kick while yelling "FLASH KICK!", my second favorite was leaping and grappling while in mid-air. A couple of times, I would grapple someone at the apex of my jump, and THEY WOULD GO FLYING!!! I was like a damn slingshot and that Chua was the ball bearing flying at the neighbor's ass.
Once, they actually flew INTO A WALL, as in INSIDE it! What made it even better, is that they were carrying a moodie mask and didn't know how to drop it or get out of the wall.
Has anyone been able to duplicate this? Or even tried it? Does it only work on those bastard Chuas?
