Ressist debuffsFollow

I am looking for a list of debuffs that stack with mages /shamens Major debuff lines ie Mala Malosina, and of course Tash .. I know of Hand of Ro for druid and necros scent line, but what elese is out theere be it proc spell or clicky ?

On raids I whine alot in /gu for tash, malo, druid(fire and/or cold debuff) and bard (HoS). What sux tho is I can only check if HoS is on or not.. That I do with my staff of elemental flux. If I get msg that I cant land it I know HoS is on cause they dont stack. You asked for proc aswell.. Wizards get an AA called pyromancy, it procs when using fire nukes and is a DoT and debuff. 500 dmg/tick and -50 resist to fire that stacks with everything I think.
Probably more stuff out there aswell.
