u/Apprehensive_Net_134

I am running Tristan Tioreh Guila Escanor right around 31 cc rn, with no legendary engraved sets yet.
Couple questions I suppose -
Who should I be focusing on getting a set for first?
Is there a specific farm route to get the gear needed for engraving?

I’ve mainly been running world bosses right now as they drop the best gear (WL4) and am not entirely sure where to go from here.

Happy to give more info if needed, but figured I’d start here.
