Triple stasis resist mods & 100 resil. Subjagators ice can kill you with resist mods I used the call, graviton lance, rocket, prismatic for the extra nades helps a little, use bleak watcher & turrets if on warlock Concentrate on the adds every wave, stay behind cover, pop out & shoot subjagator with heavy or the call. No rush so take your time. Relic part simple, break shield & stand in light pool to protect yourself. Repeat until sword phase. Try to look for heavy before you transport to the next room, you can even try to farm a bit by killing the thrall before you activate. 2nd part same, adds, then subjugator, whilst keeping an eye on the darkness timer, refresh that just after a witness attack so you don't get caught out. Again, grab relic, break shield, refresh timer, stand in pool, then damage him, remember adds too. Done. Very frustrating, just practice & patience.

[quote]Even when I think I do everything right, I end up getting blasted by the Witness and have to start over. If anyone has any recommendations on what I should do, like what weapons I should use, what stats I should prioritize, etc., it would be greatly appreciated.[/quote] Red death, rocket side arm and heavy machine gun. Learn the spawns and clear adds when they spawn. Plenty of cover you just need to pay attention to the witness doing their attack.

If you are playing as Warlock, with Prismatic: I would suggest, for second please, get to the buff areas quickly. If you have it unlocked: Hellion- great to do damage to bosses from far away, while also having a rift. Add in Bleak Watcher as well. Great for being able to control areas and or do damage from a distance. I used the in game Fireteam Finder, and it worked well playing with others to get the encounter done.

For stats always prioritize resilience. For mechanics: Boss 1: Stick to either back middle left or back middle right statue. Then kill adds on that specific side and the grims that come to you do not kill every add as this triggers respawns. Boss 2: Grab a buff then immediately beeline to the next shield room. From there you have access to 2 buffs while being in a safe room. For weapons have weapons you feel safe plinking the bosses health with then just safely shoot to victory.

Facing the area stay on the back outskirts to the right. Anchor yourself there. Use Graviton Lance. Focus on adds as priority. When Sub summons ice MOVE it’s his shattered attack. But not in the open for the witness. Once the attack is done, go back to that spot. When shield phase happens. Do the mechanic, then return in that spot. Machine gun to finish him off. Second sub same strategy. Also in the back row you can juggle between to seed pods. Don’t panic or run out for ammo Chip him away and get second shield. Do the mechanics. Once done and out, go back to the right but this time anchor yourself in the side room with the shield. You have a seed pod at the entrance and another close to the shield but outside. Fun fact you can shoot it between the bars and get the benefit. Stay in there and juggle between the two seeds. Enemies don’t come in there at all. So you can chip away at the remaining health. Keep notice of the witness’s attack as you can still get hit with splash damage in the room. Use range supers and machine guns. For special use the new grenade area denial frame.

Stay behind the statue right by beginning

Don’t focus damage. LMGs are good for this exact reason. Focus on surviving. Don’t be risky unless you can get out just as easily. If you need to, use a different subclass than Prismatic. Solar is pretty good.
