It is very simple. I discovered it on some ding 70 server(instant 70). I had mage with dagger and off hand weap. and I have found staff probably from scholomance that gave +20 int. to party members in 20 yards for 15 mins. I did a very easy macro for it something like
Code:
/equip the-meaned-staff
/use the-meaned-staff
/equip main-hand-weapon
/equip off-hand-weapon
I push this macro and I saw it stole me some intellect and stamina, I pushed it few times more and in my character options (C) i had few points in intellect and 0 stamina and I had 3500 hp and 3800 mana about. I'm describing situation before the bug came. Then I pushed it one more time and ding my intellect jumped to 440 Milions, so I had about 600Milion mana and 50 000% chance on spell critical. I tried this with my warr then and I was able to bug same way my strenght and stamina, I had 440 (or maybe 44 dont remember) Milion hp i had attack power as high as I can one hit bosses (about 1.6Milion dmg) and i had 95% chance on block parry and dodge (btw with this incredible strenght it said I have 95% chance to block 255 000 dmg ...). I'm really sorry guys that it isnt working anymore on server where I play and I was too happy to taky any screenshots. I'm not sure you will trust me without screenshots but i don't mind, its your opinion. Sorry for my bad english its not my maternal language. Btw this bug won't bug your stats everytime and basically it can only bug stats of your 2hand and off hand changing(I think it haven't anything with main hand weapon). I tried it for all stats with some off hand +8 all stats but it hasn't bugged me, just stole my stats to zero. I can only sure say, if you will try this and it will stole your stats it can propably bug them to milions of that stat, but if u change the weapons and nothing happen, that mean on your server it won't work.
