Minion Master Assassin's Promise

I have found that in 4-man Hard Mode content this is the best way to do vanquishes and Winds of Change. It role compresses a Minion Master, condition removal, & a Ebon Vanguard Assassin Support + Assassin's Promise spammer all into one build. I’ve done all of the hard-mode 4-man content with it and can recommend. Even in modes with too many ghosts and not enough corpses, looking at you Tunnels of the Forsaken, this build shines because you can fall back onto PvE skill spam.

Staff for when you’re in Minion Master mode, spear & shield for when you lack corpses and fall back to PvE skill spam.

I have found it’s safer to stay behind the minion/EVAS and have a big energy pool than try and use armor Insignias, but your mileage may vary.
