Now this attachment idea is a little selfish on the part of me just loving to be PUP only. It'll be unfair to SMNs but it's already a little unfair that BST's have this on their pets, and it's already been brought up before too (at least I believe it has),

Salvager:
Wind based attachment x2 or x3
Grants automaton "Treasure Hunter" +1

One wind Maneuver= +2
Two= +3
Three= +3

Capps out at +3
Unlike THF it doesn't have a chance to go higher on critical hits.

What do you think?
Too OP? Too Game Breaking?
