Warbringer can fairly easily get more than 95% chance to avoid all damage when combining Turtle Charm and Acrobatics together
Turtle charm - you can block all damage from hits. With svallin you can still get your block chance up to 85% (after "lucky" calculation) pretty easily. Acrobatics - with pure evasion gear and wind dancer it's not too hard to get 75% chance to evade all damage from hits. Block and evasion worth together just fine so this is basically making your chance to avoid all damage from hits "lucky". With 85% chance to block and 75% chance to evade, your chance to avoid damage is: 1 - ((1 - 0.85) \* (1 - 0.75)) = 96% chance to avoid hit. So only around 1 in 25 hits will actually damage you. That is with relatively good gear but not perfect, using like T2 or T3 affixes (ordered like poe1, that is what PoB uses). With completely maxed gear, I can get my evade chance in PoB to 85% and block chance to 90%. With those numbers instead, chance to avoid damage is 98.5%. So 1 in 66 hits actually connect. For those that don't know, you can block/evade almost everything in the game with turtle charm and acrobatics respectively. Only a few boss mechanics cannot be blocked/dodged. One that can be is arbiters [circle minigame](https://youtu.be/Flyna3xf1lI?t=116) and I actually beat him with a zdps warbringer this league, failing this mechanic 5 times in 1 fight. Just happened to block. With both turtle charm and acrobatics you would not need to be lucky and would expect on average to be able to afk through that phase and just not get hit. The only reason this really didn't work before was you would need to go full dex for evasion, but the only dex weapon was a bow so you couldn't block. Now, with a 1h melee weapon, you can do dex for evasion and also block at the same time.
