When thrown and detonated (heavy attack) this red crits consistently as it has over 300% crit chance. You will get consistency even with a slightly worse riven if you load up Gladiator mods on your Sentinel. Do what you can to get red crits as the 3x damage multiplier makes a big difference.

In simulacrum this kills level 135 Corrupted Heavy Gunners in one throw and one bleed tick (the slash proc is guaranteed). That's the highest level I can spawn, but it'll also drop Feyarch Specters in a couple of throws.

Works even better with [Khora]'s Ensnare, [Nidus]' Larva, or [Vauban]'s Bastille to group enemies up. Viable alternative to [Khora]'s Whip.
