Places of Power challenge tier 3

zEmp lead works well with high relic sith (4 of Malak, Nih, Bast, DR, Vader). The trick is managing the debuffs so that you are always taking a turn. It's extremely important that you manage the last jedi in each phase to have as many debuffs as possible when they die so that you have 100% TM on most of your sith to start the next phase (especially 4 & 8, but all of them can be dangerous). Culling blade is the most reliable way to do this. Debuffs are hard to land so having Bast helps Palp land debuffs, and your should use Malak's basic as much as possible to spread tenacity down (when he's not using drain, basically).

This assumes you can survive the initial P1 attacks with all 5 standing, of course. If not, T3 may not be for you.
