Meh okay found it, it looks really good but the benefits dont really show in game i've got 2 vet 2's, the rcv dmg modifer is probably the best.
Vet 1 Rcv Dmg 0.85, Spd 1.1
Vet 2 Pen 1.15, Rcv Acc 0.85
Vet 3 Pen 1.15, Dmg 1.25
I bet at vet 3 it penetrates everything.
I've been lied to again. I was told it was the same...
I've gotten one up to vet 3 and it was pretty angry, and yet it pretty much auto pens.
