The server i play on is 3.3.2a. THis has been working for the past 4-5 patches and still is not fixed. It use to work in arena, but when they patched it, I find it not soo useful anymore. I have not seen anything like this in any forums i visited and is originally found by me.
So here we go, THe item u need is the "Endless Healing Potion", obtained by getting 450 alchemy PROFESSION. This also works for the Endless Mana Potion.
Then make a macro say:
/use Endless Healing Potion
/use Endless Healing Potion
/use Endless Healing Potion
/use Endless Healing Potion
/use Endless Healing Potion
5 Lines only. and What you do is, enter combat. For eg. Attack someone or if someone is attacking you. Then spam the macro as fast as possible you should see your hp rise up.
After you healed yourself. Try to get out of combat so you can reset the cd of the bottle. For some reason after u used the bottle. the cd does not get a reset until you leave combat.
Ive healed up to 20k. Use to be a 3mins cd with working arena. Now its 1min non working arena and less healing effect.
Again this works for both mana and hp. I am the originally founder of this, havent found it on any forums.
Reason why i feel like posting this is because, i havent contributed for awhile.
Ill post some screenies when i get 450 alchemy on my priest. I deleted on my warrior T.T. ENJOY and play safe
