One thing that's very nice for the gods, and not cheaty at all, is to get two seduction critters, and present yourself to them : permanent stunlock from enticing.
It doesn't use mana too, so no problem.
You can just have one or two bruisers, the rest seduction, and pick them off at your leisure.
It takes care of the overseer, so the only problem is the horror ( and others creatures ).
Batgirls are the best, flying and high speed, so you can easily get them in position for them to get in position.
Need lust dmg genes and traits tho, enticing from 0 lust without close to 100 lust dmg is a crapshoot.
Edit : Just thought of a combo : Lymean/lymean starting essence gives shield when healed, a lot of succubi subspecies have healedonfucked (heal when fucked is mg), could be cool.
Edit edit : Unrelated, but just noticed that clicking on max genes button with fusion focus enables you to go beyond the gene limit if you can raise it, e.g. my limit is 10 yet i can make an anglerfish with 11 hp/mana/fert/vir genes.
Sounds highly exploitable, especially with the equality creation world modifier. Some can be more equal than others.
