How much hp for a mage to survive Zakum run?

I have about 840hp and 3300 mp. Is this enough if I hug the left corner? I heard Zakum can do 3.2K from some people and I heard 4.2K from other people. Which one is right?

Thanks

 

the former. you have enough hp for zak though it does do 1/1s, don't let that catch you off guard

 

3.3k to be safe but as a mage you won't die in 1 hit as long as you've magic guard and...don't standing on top of the zak. Just make sure you bring some holy water or all cure potion in case you're sealed but your magic guard ran out of duration.

 

What if I have maxed Dispel. Does Dispel work against being sealed?

 

Ah yes that'll work too.
