I've got a solid concept for a build but I am mostly familiar with left-side-of-the-tree pathings and itemization (done more totemplar builds than I have fingers). I'd like to request your wisdom and improvements to something I really want to league start with.

Concept:

1, Frost Blades is getting a large added damage effectiveness buff
2, Poison likes having a large base hit and the %resist penetration FB loses from the threshold jewels doesn't hurt it
3, Trickster Frenzy charges + Polymath + dagger crit + Unbound Ailments are generic damage multipliers that scale both poison and hit - well, freeze threshold - damage
4, Heatshiver is a massive +130% cold added as fire if you can freeze enemies

---> let's try to freeze everything and make Poison do the primary dps

Pros:

- Longest weapon range strike skill
- Enough freeze threshold to even freeze Pinnacles (using Southbound and Expedition's End)
- 2 ascendancy notables free to spend on Trickster defensive layers
- Capped spell suppression, Ghost Shrouds
- Freezing everything in the Sanctum should be an excellent way to avoid Resolve loss
- Dodging boss mechanics when they have 70% action speed is ez pz
- Best mods on rare gear are super weird and unsynergystic (increased cold damage, Chaos DoT multi, physical damage dagger, chance to poison) so should be relatively cheap(er)

Cons:
- Still a strike skill tho
- Unique heavy -> chest, gloves, helmet, maybe-amulet are uniques so resist juggling is likely hard
- Needs a few specific (though common) Cluster notables for freeze duration
- How strong is screen freeze as a defensive layer?
- Could use some maximum resistances, evasion, IDK just more defense?
- Ability to freeze bosses is a hard threshold and needs to be met for full boss dps - taking out Perfect Agony before good gear is not a massive loss in dps for the 30% less hit dmg penalty going away

Any ideas for improvements? I also welcome endgame gear goal suggestions to see how far this could be pushed.
