We all know Presence on us, buffs up companions, I just recently found out if you give your Companion a Item with Presence, their presence goes from 0 to whatever the item gives them.(Currently 2 Implants with 40 each, so total of 80)
That Presence ALSO buffs them, very well too. I gave Broonmark an Implant with Presence on it. x2
He got additional 400 HP, +16 more DPS, & 11.2 Healing bonus, I found that rather neat, was not sure if anyone else knew of it. My Presence is 312, so he also got 1570 HP, 62.4 added Dmg, 56.7 added Healing. Makes wonder if stacking more presence on a companion will help out in the long run.
