PoE Trauma builds

(DISCLAIMER: This is my first post here, if I'm breaching any etiquette, please let me know) After I was lucky to drop a Mirror this league, I splurged half of it on an unnecessary expensive Poison Molten Strike of Zenith Slayer. Now, with the remaining half lying around, I wanted to try a build I've been sitting on for a while now (ever since I saw a video about The Flawed Refuge), which leads to this build. I got most of the gear ready, and the build already works while I am Lv 74 at the time of posting this. No showcase bc of my potato PC, but visually it should look like any Double Strike

Power charge gain: 5% on hit from mark quality 50% to gain on crit from flicker of power q20 10% from ascendancy 65% to gain, hits per attack = 88% chance to get a power charge. If sustain is bad, use power charge on crit to get 100. Early on prolly start with normal flicker. Transition to crit later.

Always wanted to play Glacial Hammer Currently, I want to confirm that I will self-injure myself with a high frequency of Trauma to maintain the state of less than full blood. Maybe paired with Strength of Blood to reduce Trauma's self-inflicted damage? POB(1): POB(2): In the above two POBs, Trauma's self-inflicted damage is very high after turning off Immortal Call. (2) is the lowest configuration currently But I don’t know the feasibility yet. Which one is better

POB: This build uses 90% Ele Res (achieved with Tattoos+Purity of Ice) and 100% Phys Taken as Ele to mitigate the damage from stacking Trauma for big Frost Blades damage and near-immortality!

stacking flask effect with tattoos so im 100% phys dmg taken as ele, convert phys to ele to chaos with original sin, then stack +proj (with nimis). trying deep delving atm (almost 600) surviving 300+ trauma stacks but nothing lives long enough to go higher. tried tanking uber maven memory game (with immortal call) and took like 700 dmg. potential upgrades are mageblood 3 flask with skill duration along with double implicit dawnbreaker to cap phys dmg taken as ele
