[Archon Flow] doesn't really matter past level 50 were [Frost] won't be outright killing with his 4 so [Primed Flow] is effectively the same. Molt augmented with [Corrosive Projection] and [Umbral Intensify] allow [Frost] to fully armor strip with one cast. This build works best with a few casting speed Amber Archon Shards and [Corrosive Projection] can be removed if you add 3 ability strength Crimson Archon Shards. [Streamline] is just for ease of use but can be swapped out for Cold Force, [Natural Talent], or any other mod you would like.
