Help with cauterize DoT

Is there any other way to survive the DoT from cauterize besides Ice Block?

I try to hit Mage Armor and Mana Shield before it kicks in but I always die to the DoT unless I have Ice Block off cd.
Mana Shield and Mage Ward. Often, in PvP, those two won't be enough because of the other incoming damage. The best is to have a healer heal you or to Evocate glyphed (other than Ice Block of course).
Yeah, I'd put up shields and be prepared to Evocate if needed.
Awesome, thanks for the answers all. Guess I will start looking at putting Evocate on the short list when Ice Block is on CD.
When you know cauterize is about to proc, put mage ward up BEFORE hand. itll save you a GCD and start helping from the very first tick.

otherwise be very very ready to evo
Post-proc Mage Ward is also effective, particularly if you have good healers. I also macro it with Gift of the Naaru and any other healy tricket/item I happened to have to give my healers a few extra seconds.
Just do what I do and sit in it and blame the healer.
I thought mage ward would have been able to save you, unless you're still taking damage from whatever procced cauterise in the first place.
If I get below 40% I start kiting towards leaf spawn, If in EoTS I hope to get lucky in towers with buffs. Just a safe way to play if you get intecepted and have no choice but to fight. Otherwise try to peel and heal up before Cauterize proc. Otherwise what everyone else said pop shields evocate LoS. Good Luck to all you fire mages representing!
