Enki's Arc Witch Memorial Page & POE 2 Arc Summary

Storm Brand.

Controlled Destruction. Both have their own downsides, CD has the crit penalty, Hypo requires you to chill first.

HoT can be good early on when your base damage isnt that high yet. Wrath gets better later on.

ES doesn't actually help that much, as Mind over Matter only works with damage explicitely taken to life. You'd be better off with a Life + Mana rare chest until you get an Inpulsa's.

Looks good to me. With multimod you can only add one more prefix and suffix, i'd just add the highest available life and any resistance(s) you need.

Overall I think your character looks fine, although 4.8k is on the lower end of how much life we should have at lvl 90+, I guess. But I know how you feel. I never managed to get 6-7k+ effective life pool either, like some people here.

Since the build isn't meant to facetank, it all comes down to movement, evading attacks/proper positioning (which can be quite hard), so when you're in a boss fight like Minotaur, you have to know the mechanics (his attacks, what the boss is doing, when he is doing it etc). And of course you should definitly avoid certain map mods at all cost, because they're just too deadly.

Having that knowledge is priceless and worth more than thousands of hitpoints, so to speak. And it's simply something that comes with experience.

Look up some videos on the Minotaur fight and try to memorize the pattern. Watch out for his special attacks. Do not take the slam. Do not stand in the falling rocks. Do not stand in the lightning walls. Do not get hit by the burrow strike he does when you leave melee range. If you stay in the same spot until he unburrows, he's going to oneshot you, even if you had more life. So even 1000 hitpoints more probably won't solve the problem here.

Some bosses in this game deal 5,6,7,8,9k damage with a single blow or in a single second. So for builds like this it means, it's all about not getting hit by that attack.

Regarding Hall of Grandmasters: I assume it's impossible with this build. I tried it once and yeah... I got completely obliterated. Hall of Grandmasters enemies are player-created characters and if I remember correctly, normal game mechanics don't apply there. It has PvP mechanics enabled. So if you want to beat that map, your best bet is a build that is centered around PvP.

Any other weapon except for wands or a shield with life and preferably some damage and spellcrit.

Besides what Cendrake already mentioned, i've noticed that you're not using any mana flask nor have any other ways to sustain your mana. So, replace the Quartz (or Diamond if you get consistent crits without) with an Eternal Mana Flask with the Enduring prefix. Also upgrade Pantheon if you haven't yet and use the 3x red socket recipe to use the full Immortal Call setup. The rest comes down to learning the specific fights.

As it's mentioned right on the jewel and in the PoB section of this guide, that's the shock from Beacon of Ruin since PoB can't calculate it itself. That char has 167% shock effect, 15*(1+1.67) = 40.05.

Also remember that multimodded doesn't necessarily means it's better in any way. In case of my ring and helmet it just assures me to put on the resistances I need after GGG forcefully changes yet another thing with major patches.

Don't be too fixated on PoB. I've done all content with this build for the past 4 leagues with just budget early-league gear, 400-500k Shaper DPS with shock calculated will easily get you there. As for high tier maps, damage is barely needed there to begin with.

Can't take a look at your char because the character tab is private.
