spell id 28772 - This i the debuff that would be on the effected target of the frostfire set bonus when hit by a damaging spell and successfully procced. It would last for 30 seconds and once the first damaging spell to hit after this procs, increases the spell damage modifier of that spell by +200 considering the spell power coefficiency ratio so for instance if the next spell to hit was 'moonfire' it would only increse the damage of the spell by like 75 and elemental vulnerability would dissapear from the target.
