I don't think there's anything in terms of enhancing avatars, just cure set/stoneskin/melee(lol) pieces
Looking at Julians dat mine there's a few nice pieces coming out from legion, earring and legs with "enhances blood pact damage" and a couple of hands that have avatar mab+5 and a HQ with +8 mab.
I doubt SE will give smn anymore improvements, look it this way 18 smn can basically take down almost anything in game. We already having free avatar out, the only thing we want from gear are more skill or bp dmg boost and SE never like damage boost because of BARANCE issue. This is also the reason why they not lower that bp timer cap.
Nares are better for Magic pacts, but yea, Auspex/Spurrina Gages are the best for physical pacts.
Does the attack enhancement on these gages actually do anything or is it like the older Enhances pet attack gear we had access to? To clarify, I am not referring to the Enhances Blood Pact Damage aspect of these hands.
Summoner's reward in VW is being able to mooch a run by just sitting there and maybe using a ja from time to time while getting gear for your other jobs.
