Party/straight dd - apoc rr san scythe
Tank (drk/mnk) - apoc rr gnarled horn ( can sub apoc or rr for laughing or w/e counter atma aswell)
If just procing stuff you can do apoc rr sea daughter but thats just raw proc setup
Dont bother with epeen ws dmg in abyssea, even before relic ive hit 1k crits with my general dd set, if you really want tho i guess sub ss for stout arm, but it really is a waste.
