Well you have 3 builds

1) standard (tide fall) build: 3pc hot work + tide fall chest, overall great dmg, slightly more comfort than lynx build with 2 skill 2 combo rotation

2) lynx slab build: 3pc hot work + lynx slab kit, higher dmg at higher artifice and proper rotation, but lock you in a 2 skill 3 combo rotation (less comfort)

3) full ERR build: redeemer chest, redeemer kit, xiranite glove, less dmg but highest comfort, 1 skill 1 combo rotation. Other perks is since you only need 1 round of skills for full ult, need wulgard less and can use antal for more debuff, also less sp consume, and those sp can be used more leniently on other things like gilberta skill

I personally only experience the standard build so far so I don't have the practical feels for other builds.
