GUIDE TO THE LRSF SLEEP METHOD
This requires a mind dominator that has permadom. You need mass hypnosis and mesmerize, both well slotted for accuracy, sleep, and recharge. The kismet unique and tactics can help as well, but are not needed. You also want a brute on your team with taunt and a ranged single target attack. Make sure they do not have any procs in taunt. Furthermore, you want some sort of stealth. Super speed plus a stealth IO is what I use.
So, the heroes are situated on a platform. During the cutscene, Statesman will activate unstoppable. You must wait until unstoppable drops before doing anything. This usually takes about 2 minutes and you can tell by the aura around him. Everyone except you should be away from the platform. Once unstoppable drops, go right under the edge of the platform (with your stealths on). Do mass hypnosis by jumping up and activating it, so that it happens once you are back under the platform. If you miss anyone on this first try, just wait until mass hypnosis recharges. Do NOT use mesmerize yet. Keep trying mass hypnosis until it does not miss anyone.
Once you manage this, you will keep hitting mass hypnosis whenever it recharges. Use mesmerize on anyone that mass hypnosis misses, as quickly as you can. Use the jump method for mesmerize as well so that the heroes have no chance of hitting you. Tell the puller to pull. They should wait until right after a mass hypnosis, then taunt, and then use the single target ranged attack. The order in which they pull does not matter, as long as Numina is last. This is because, on occasion, if you pull Numina first, she will start clear minding heroes. I recommend pulling manticore first, as he is the only hero that has powers which can hit you below the platform. Be sure to stay away from the puller, as you don't want to be hit with any AOEs.
THINGS THAT PEOPLE DO WRONG
- pulling numina first
- not using a brute with taunt and a ranged single target attack. it can be done without, but you need to be extremely careful to not wake anyone else up and to keep aggro from the mind dom
- not using mesmerize the instant mass hypnosis misses someone
- using mesmerize before your first succesful mass hypnosis
- letting dom drop
- not doing mass hypnosis as soon as it recharges
- not waiting for statesman's unstoppable to drop
- not using some sort of stealth. it can be done without, but you need to be extremely careful about getting your first succesful mass hypnosis
- trying to use the sleep method after already screwing up. if you've screwed up, it can be salvaged, but it's often best just to let the mission reset by logging out
