I fucking did it.After 3 hours of having skill issue i finally did it.(Granted it was a 2 turn orgy and i for the love of me cannot even imagine how to have a 5 turn orgy like the kind stranger before told me to as a general pointer but hey i finally did it)
(P.S I would rlly appreciate someone explaining to me how is a 5 turn orgy even possible)
Haven't played in a bit and have foggy memory, but the method I remember is to use a decent commander (at least 3 caps), stack trauma levels after ambushing the first chosen, capture the 2nd chosen immediately and do the same (with a focus on your chosen circumstance for orgy), surrounding the 1st when they escape, capture the third one and repeat. Keep an eye on extermination and avoid capturing any chosen until the last surround is about to expire, then capture the chosen with the highest surround turns, using the punisher move, 2nd most (or spend turns upping trauma levels if uneven and you want to try for a longer orgy). Finish off on the third and you should (hopefully) have a decent orgy.
The reason to hold off on the surounds after exterm finishes is to prevent the chosen from flying off, making it impossible to surround them unless you have the augmented commander with the relevant upgrade and a capture charge.
If you have the item Inevitability, you could take the 1 EE hit to make your moves 10x more effective (free surround level for each trauma<---) and maybe get an extra turn or three on the orgy.
Also, save before you go for the orgy in case you mess up or want to change the beginning of the day (chosen targeted etc.).
The circumstance you use is semi dependent on your chosen but a good starting move for first capture would be pummel or grind for the circumstance boost, then humiliate to make damage accumulation on the other 2 easier to do.
Also consider how long it takes for each chosesn to get reinforcements. Example being that if I wanted to damage chosen 1 as long as possible, I'd go with a personality type like the red colored Reaper (6-8 turns for first reinforcement to appear) giving me an extra surround to stun Reaper with (not participating in exterm) while I work on the other 2. Sidenote on stunning is that you will want to at least pummel on surround stuns to get the pain trauma to attribute turns to the surround counter again as surround turns it off at the current level. (surround at pain lvl 2 means that pain won't tally in to the total until it becomes level 3. This is something to be mindful of as losing your pain levels could mean that your shame levels don't either, and you suddenly can't surround the chosen. Totally hasn't happened to me a few times :-D ).
