How much hp do i need as a cleric to survive a zak run?

I've already finished the prequest and i've seen that the maximum dmg zakum can do is about 3.1k.
now, being a cleric i only have 875 hp, but magicians have "Magic Guard" which is a skill that replaces 80% of hp dmg as mp.
is that enough to survive a zakum run? and if not how much hp should i have?

btw i have 3.3k mp if that's something you need to know

 

don worry Mage always can go zakum as long as rmb to cast magic guard

 

Great, thank you!

 

I also suggest having auto pots so that you're not manually healing!
