What enchants would work best on:
atlantean gs
triasta of bronze
kai sabre
vindicator
ravenwing
and as for greases, which are worth the damage reduction?
are any better with certain weapon types over others?
I usually go with dense for weapons I primarily do damage with, or ardent for mobility-centered ones or just ranged in general, excluding guns. But, the best enchant depends more on what skills you’ve put on those things.
As for greases, there’s a youtube video for them
Dense, Scorch Grease from personal experience.
