I willingly admit that I suck at the game, but I'm struggling with how to deal with elemental damage on this build. I'm around 105, and most of the content is just cakewalk so far, nothing physical hits me. But, for example, trying to get to the sunless angels and kill them without dying is a nightmare.. half the time I literally don't know what's killing me, I'm nowhere near the ball things but getting damage "pulsed" on me repeatedly.
Is there a lot of merit in moing some leech or life on attack to get through it? This is the first in your face melee I've leveled in median, and most of my other characters reaching this point have 80% all res from pgems still, while the warrior is using runes and thus stuck at 75.
Am I missing a vital piece of the puzzle? At ~105 I have ~305k def, ~6.5k life, 50% phys res and all res capped at 75%. For what it's worth, deathgaze damage is 1.3-2.4k or so. Using pretty much completely TU4s as suggested. Should I be trying to upgrade to crafted stuff at this point? It's not something I've looked into a lot, maybe I'm just making my life difficult by sticking with the TUs?
Is it just a matter of git gud and doge the stuff? What am I actually getting hit by in sunless sea that I've barely noticed on other characters?
Edit: Watching the videos in the OP you go from 6.5k hp on death laser thingy to 8.5k in sunless and gaining ~600life per attack, so I'm surely missing some upgrades and leech.
