HP fooling

[Balance]

I've been playing around with the damage taken. Errrr, I should say, how it appears.

So say I take 13 normal damage from a mob, I grab that block it from the client, send back. Now My client shows I take no damage, but of course eventually I die because the server knows I've lost to much HP.

I was wondering if HP is completely kept up server side? I figured we could somehow do something similar to the cooldown hack for HP.

the chinese are just genius', to figure out and COPY what they did with the no cool down for hp would take much work.
