How do curses and/or DoTs stack?
Corruption, immolate, CoA and CoD can be cast by as many warlocks as you like, taking into account the debuff limit. There can, however, only be one CoS, CoEl, CoW or CoR be on each mob at once. If another Warlock tries to cast CoS, CoEl, CoW, CoEx, or CoR on the same mob, it will overwrite the previous Warlock’s curse. The effects of CoS and CoEl apply to anybody dealing the related schools of damage.
