This looks like the [Cryotra] 2.0. Nice Sentinel weapon. Should make for fast viral procs.
Added Later:
I now have this, and as speculated, this build is probably the strongest sentinel weapon there is. It kills dudes on the Steel Path. Stat-wise, it's essentially a Glaxion, but in the hands of your pet. :p That's 500-ish damage per hit, 17 hits per second ... with almost 100% status. Max viral almost right away, electricity to 'bleed' them and stun groups, and if you put that with your [Nautilus] with Cordone, you'll be stunning those tethered groups of enemies.
The Nautilis is okay. I put this Veraglas on my Moa. :)
