Sooo, in lack of other things to do (while I been waiting around for my pals to come online) I been chasing the new companions like crazy.
So far I got the: Vizir and Paraoh Predasite, and the Sly and Panzer Vulpaphyla.
For those interested, here is the complete description of their mods, literally citated (all of them are maxed out): Vizir:
1) Iatric Mycelium: "Release a trial of spores every 8s that heal the companion and its allies for 300 health over 5s."
2) Acidic Spittle: "Every 5s spit acidic tar at an enemy within 30m, blinding them for 12s and dealing 120 Corrosive Damage."
