hexblask occ quesion?

it look like all the video i watch, the HP pool for occulist is very low? is it a squishy build but has alot dps? or there are other ways to compensate the low hp

the point of running occultist over something like shadow is for the power charges, where you utilize the crit + dmg to burst through bosses before they can react, and it's mainly to farm sanctum.

you can kinda mod it to have more hp with mind over matter + eldritch bat and play petrified blood or whatever but you sacrifice a lot of dmg in the process.
