@Chapstick - I can believe that. I put two Alphas on the same screen and made them move around in a circle, the aura effect made it lag pretty hard. Hopefully they fix it...(Err well..people seem to like the slow motion thing and it does seem harmless..I don't know ahaha.)
@Zero-chan - Ahh, had the PB thought mixed up with Phase 4. Jacky's 7P+K is his PB too I believe.
With 9PK~6P+K~9PK on a guarding opponent after you do it a couple times with the opponent against a wall the game starts to lag pretty heavily 0: Too many Kasumis and petals on screen
@Chappy - You are using Kasumi right? Her PB animation ends quick so you probably have to do it around 00.25 in mili seconds. Also it only works on those danger zone stages that have those orange effects on it. (Helicopter, Buddha, Depth Metallic piece and Buddha statue.)
Video of a powerblow glitch that causes hit effects to slow down.
With a little extra fun time fooling around with it.
EDIT: You do a PB within the last seconds before time runs out on a danger zone. Works on Hotzone, the bottom portion of scramble and even the buddha statue.
