PoE Shockwave Totem, Cold builds

In 3.14 that was my favorite build, unfortunately, that build lost more than 1M dps in 3.15 due to various nerfs But this time, with the buff of the Skin of the Loyal armor (from +1 to +2 gem lvl) and the new mastery system, i managed to get back to its original 3.14 strength! PoB: It can go up to 4M with a watcher eye! but that gets way too expensive! EDIT: 3.8M with Hrimsorrow unique glove! league starter friendly! (except for astral projector ring!) EDIT 2: I edited the tree, went more on the shadow region for crits
