Certainty regarding You Must Be Happy

[tipsyConfection]

Is there any Concrete and Certain List of Buffs/Debuffs per Time for YMBH?
I just wanted to do Hod's suppression mission using YMBH, which trivializes the whole thing.
But i also don't want to kill my employees by overbuffing them, so i want to be sure when to stop.

Only trick I know about You Must Be Happy is that it can't buff past 100 stat cap
(at least, until you raise cap trough other sephira).

If all your stats combined are above 200, then it can't give you more than 200 extra. I used this trick to run abnormality for several minutes to unlock it's information and ended up with 100 in all stats without dying. "Yes" and "No" flash too fast to choose at that point, so it's 50%/50% whether you raise all stats to maximum or drop to minimum.

As for Hod's suppression, I picked all easy abnormalities for that run and trained 2 agents to max stats in normal way.

Hm, interesting. Sounds tricky though. I recall that using that tool too many times with the same person causes them to explode and die, too. (If like what, an employee used it 5+ times or so in a day?)

And if you're really having trouble with Hod's, you could also choose one employee, buff them royally up, to degrees where they'd definitely die, and have them do all the (hard) work. Once you beat it, you could load a memory repository checkpoint, or just take the sacrifice of one employee. Heck, maybe you could even buff a untrained rookie to insane levels.
(Ideally put said sacrificial employee in armor that you can replace if lost once they die, or you might lose some good armor.)

Since core supressions stay complete, you totally could make sacrifices or complete it with casualties and load a checkpoint, missing only some gear potentially.

And since stat reductions affect combat quite badly, i'd suggest using the ultra-buffed employee to gain energy as optimally as possible (ussually by working HE or above abnormalities exclusively for high energy gain so you reach the cap faster without having to do as many meltdowns, although this might not be a big issue with Hods, but it may help alot during others).
