As you know 3rd boss in Mogu'shan Vaults - Gara'jal the Spiritbinder - casts on his current tank and 3 persons (in 25 man) debuff Voodoo dolls Voodoo Dolls - Spell - World of Warcraft - and all damage which is done to current tank is done to each person with debuff. Boss has 2 types of abilities 1 instant cast and typical melee hits (~20% due to this thread can be fully avoided).
What to do:
Pull boss and wait until he casts voodoo dolls on main tank and 3 other persons
Paladin's Hand of Protection - Spell - World of Warcraft casts on current boss tank and boss won't change his aim as he used to do - he will continue to hit tank with Voodoo doll debuff, but because of Hand of Protection - Spell - World of Warcraft tank won't recieve any damage from boss melee abilities for 10 seconds and this can be repeated practically every 60 seconds if you have a lot of pallys![]()
This is pretty useful when it is necessary to save persons with voodoo (for ex, when they have critical level of hp) and they won't take any damage from melee hits except boss's instant spell cast on tank (in heroic mode each melee strike ~90k and it is copied x4 times to persons with Voodoo Dolls)
