HELP ME!

Can someone please look at my current necro and tell me why im still so squishy. I have 100% spell suppression. I have been following a guide and it shows their effective hit pool is like 315k and mine is like 50k and i have no idea why.

You dont have a way of really negating physical damage, your armor and evasion are both low. You have good resistances obviously and spell suppress/block but nothing much against physical attacks. I would maybe long term try swapping out purity of elements for defensive aura. Maybe determination and then since your on that side of the tree get an armor node or two. Put in a stormshroud jewel and get avoid ailments/reduce shock on boots. Try to get armor where you can, a few tweaks and you can probably double your phys hit which would feel alot better.
