This build is best used with the Naramon focus school and/or [Ash]'s [Rising Storm] augment to maintain your combo multiplier.

Equip Gladiator mods on the [Deconstructor] (Prime) of a [Helios] (Prime) sentinel for an additional boost to critical chance per combo multiplier.

Equip Arcane [Fury] and Arcane Strike for even better results.

In my simulacrum testing against level 105 Corrupted Heavy Gunners and Noxes, I found that viral outperformed corrosive. Only against Juggernauts did corrosive outperform viral (I assume this applies to any enemy highly resistant or immune to viral). Forced bleed procs on dual dagger combos means [Fang Prime] works well with viral despite focusing on puncture over slash.
