Rolled a Heliocor Riven that folds Primed Reach and Primed (or Berserker) Fury into a single mod which is not min-max but is great QoL. Been on a Specter kick lately and (if you didn't know) Synoid Heliocor allows you to convert one enemy to a Specter with a HA kill, so here's a fun little armor-strip crit build for that. Supports swapping [Berserker Fury] for Faction mods if you're into that.

If you really, really wanted to go ham with this (or a similar Riven) and have too many Umbra Forma lying around (yes, just not to the point that I'm willing to spend one on this) there's a neat alternate config: Madurai Forma [Voltaic Strike]'s slot, Umbral Forma the first slot and put [Sacrificial Steel] in it, [Sacrificial Pressure] in [Gladiator Might]'s slot. Now you can chose whether to leave armor strip intact or slot Faction mods over Voltaic Strike (for an absolutely brutal Toxic-crit anti-Corpus build). Or just [Berserker Fury] for the fastest Toxic crit hammer ever.
