General

Face accessory you can cube the blackgate mask for tradability but really its pretty much only good for drop since the main preference is with sw otherwise for a lower tier potential, you can cube a branch nose or something

Cyclops eye lv3. Gives 20% drop per line & tradable with psok.

For tradeability, any will work (Racc, mask, branch)
For potential (is there a big difference in %drop tiers?), SW glasses
