Slash status procs don't bypass shields, and are terrible against robotics. Toxin status procs are terrible against robotics, neither can they bypass the shields of Treasurers and bosses, which includes Sisters. This weapon does puncture, magnetic, and electricity damage, with an option for radiation damage from the alt fire. This covers all health types found in Corpus units with damage bonuses against each of them, with the exception of Flesh, the Corpus health pools of which are so low that they are a non-factor.

Not enough status chance and unique types to rely on [Galvanized Aptitude]. Replace [Primed Shred] with a +Critical Chance mod? Exilus mod is personal preference — I don't see any that offer notable advantages.
