Sepulcher of the First Ones Warlock Guide

The builds listed here are all assuming you have acquired your 4-piece tier bonus from Sepulcher. It is important to note that certain builds do change upon 4-piece acquisition so I encourage you to check the spreadsheet listed here (under the sims tab) if you have not yet acquired tier.
All legendary recommendations are also assuming you are playing 1 Covenant legendary baseline. I did however list Decaying Soul Satchel (Night Fae) in a few places you might play it over others before acquiring your second legendary.
