I just took anything synergizing with cold damage and put it on Frost and it works pretty well!
Frost
- Biting Frost augment
- Arcane Ice Storm
- Freeze Force augment
- Icy Avalanche ofc
Tenet Glaxion
- Shivering Contagion
- Primary Frostbite arcane
- Photon Overcharge (still missing this one but soon I'm adding it too)
Glaxion melts everything in front of you, spreads cold like crazy which also adds ability strength and duration due to arcane ice storm, you have huge crit chance and dmg, you have excellent armor strip and can easily generate overguard.
Since no merciless on glaxion you have to run serration but if I had max rank arachne I'd maybe try that instead of arcane grace once I have photon overcharge from NW. Am I missing anything else thats fun and that could be added to the mix?
Not sure if I should go with vile acceleration on glaxion or maybe add something like hunter munitions or bladed rounds instead.
In any case, it takes a bit to set up the whole build but it feels very thematic and flexible, Frost really becomes even more of a powerhouse with it, I only ever used him for his bubble until now.
edit: I'm also thinking about what to subsume over his #2 since it seems kinda useless, it is low damage and you have plenty of cold procs even without it. Nourish might be the boring but safe option?
Allies also shooting the target doesn't really make it better, in the end it still results in needing lots of hits to strip - likely more than it's required to kill.
It still sounds like this is all more due to Verglas being OP than anything to do with Citrine, if it alone accounts for instant 80% armor strip. With a companion, shards and corrosive weapon even Loki can fully armor strip then, it has nothing to do with the wf or prismatic gem.
I'm not saying it doesn't help, each free corrosion stack when near Citrine helps a bit even if you dont equip emerald shards. In my experience though, in practice, it's easier to just cast pillage, immediately fully strip that thrax centurion and oneshot him than depending on corrosive stacks building up. It's just too slow.
edit: You mentioned mutlishot boltor, I dont think prismatic gem triggers off multishot otherwise shotguns would be completely busted with it. Shooting an enemy with a single shotgun blast doesn't proc the gem a dozen times afaik, maybe it has an internal cooldown.
