This build is viable for 3.22. This guide was made before patch notes on 3.21 as I was out the country so some aspects are a bit out of date. However I have updated the written guide and POBS

00:00 Highlights from 3.20 League Start

01:15 Build Intro and important mechanics

05:10 Non Crit Version Explained

07:35 White Map Progression

09:06 Pushing through Yellow Maps

11:38 Flasks

13:03 Pushing to Higher Red Maps

17:35 Gearing for Uber Elder/Maven

18:19 Jewels and Cluster Jewels

21:52 Bandits, Pantheons & Amulet Annoints

24:23 POB Overview & Skill Gem Links

31:26 Extra Resources and Loot Filters

33:11 3.21 Changes (DO NOT SKIP THIS PART)

At face value the build loses a bit of power but I expect this will be made up and then some by the new skill trees on weapons

Looking at the new attack cluster node with +1 arrow this is not worth taking for Rain of Arrows so POB stays the same except taking the new instant leech master
