Hmmm, quickly, I would say emperor, and… maybe regeneration or Alchemist (I don’t really know what alchemist is doing, except I know it’s spiritual, and I saw spiritual freedom, some modules about love and grtitudes, harmonic singularity). I am not versed enough with Alchemist to say it would fit tho.
Well, of course Emperor would fit Iron Frame, probably stress and negativity displacement because you kinda need this to become tough.
Asclepius (not sure, maybe regeneration would handle it?), Serum X (we know emperor does help with building muscle), sanguine is partly in emperor if I remember correctly and probably in regen.
Gratitude is in emperor, temptation, aura of craving and sexiness unbound is not really in emperor, but Emperor does makes you attractive, so it could touch that a little bit. Power unleashed, pretty sure emperor does cover that, carpe diem, working hard, hell yeah!
Then, I would hope to use regen for : Sanguine, Spiritual freedom, inner voice, love without attachment, stress, negativity dispacer, harmonic singularity and maybe Asclepius.
Now, the ones that are not targeted really
- Jupiter : I don’t think there are extreme focus on increasing manifestation power, but manifestation are included in emperor.
- Inner voice : Not sure about this one, I don’t think a major title contains this.
- Sexiness unbound : Depending on the importance of sex in the custom, could see if one choose Khan over Emperor.
- Aura of Craving : Not sure this is present in any custom, but same as Sexiness Unbound.
- Temptation : Same as above.
- Joie de vivre : Maybe it is included in Regen or Emperor… Or is part of sanguine?
So this would be my anwser, Emperor and Regeneration, maybe there are some core I am not thinking about, but for me the Iron frame part is really almost unique to Emperor! Just the three first modules, you get that from emperor’s toughness, and Serum X also.
