Frost has a fairly useful kit for low-mid level content so we have focused his General Use build on just making his abilities have better QoL. The subsumed ability focuses on stripping armor as Avalanche is a fairly weak armor strip unless you pump a lot of ability strength into it. We replace Ice Wave as it's a pretty weak ability in most scenarios and is outclassed by the others.
Fire Blast is the best General Use ability so we chose it first and foremost. Shuriken is another good choice but completely stripping armor isn't need on the majority of content this build would be looking to tackle. If you do simply replace [Natural Talent] or [Augur Reach] depending on the tileset.
[Enemy Radar] mods help us to find enemies. Due to the nature of the build we need to sometimes seek out stragglers.
[Rolling Guard] is a flex mod that can be replaced with any other survivability mod depending on the difficulty of the content you're doing. Snow Globes and shield gating should keep you relatively safe but it's your call.
Arcane Velocity is run primarily because of the [Kuva Nukor] synergy but you can replace it with any other arcane that increases your damage. You can even run something like Arcane Resistance or Arcane Deflection if the enemies are putting out a lot of those procs.
