PoE 3.21 Explode totem meta abuse Uber Sirus

Build base on this guys guide but have some major changes: https://youtu.be/e8iYGZ5c04M

1. Why not trickster?

• Trickster with Chain Reaction ascend can kill uber boss instantly because all traps are trigger at the same time, other ascends can not. If you want to farm uber maven, play shadow instead.
• Trickster is too soft, lacking defense and recovery, low on movement speed, cant use Trickster to farm Uber Sirus or orther uber bosses or other contents like invitation, blight,... It's feel like you bring an zhp ice trap to do other contents.
• PF can tank all Sirus's skill (not swimming in the storm and degen in the ground becasue u cant recovery when standing on it) or all uber Shaper's skill too, 180+ ms, flasks always uptime will be much better.
• Defensive layer: 60k ehp. +58% flask effect + 30% effect magic ultility flask is almost 38% less dmg taken from elemental damage. +83% physic damage taken as elemental damage (Lightning coil, taste of haste).
• Regen 2000+ life per second

2. Why not play PF poision? Using rare Helmet instead of HeatShiver make u more tanky, but DOT cap at 35m dps. it takes too much time to kill bosses, Uber exarch/eater will enter their 2nd phase, when cold convert can one shot everything.

Item choice explain:

1. Why not convert all cold damage? Using rare quiver with gain cold, chaos dmg and convert cold make this build lose a lot of damage. I was used Templar timeless before, to convert all physical to cold damage, but it costs too much point to have 150 devotion. So timeless jewel with double dmg and global physic damage is much better. Bow base with converted cold damage is always the best, incresed global damage too.

2. Why don't use Impossible Escape Ancestral Bond to get more totem life? I was tested it, 3 cold damage node(2 big node and Freeze duration is super good with Heatshiver) is equal to 3 totem life node. But Ancestral Bond costs 17div when Hex Master costs 1 div.

Note1: You should have mouse macro or AHK for life flask. Other flasks have "reuse at end of effect" mod, but life flask doesn't, use macro will save your gameplay. Every PF use it, so dont worry about GGG.

Note2: Pob updated explode damage, but it is incorrect(Totem life doesnt increased explode damage)
