Try going Holy Nympho build, its the best.
you get high WIS and can use Holy magic(which requires some items) which are very powerful.
also you would really consider into rebirthing as a Deepone, its just a great race for any nymph builds that include Juicing, as even if people wanted to rape you then they basically feel into a Sex trap and you can juice them to death this way.
i never tried this build But it is OP on its own, see if someone else can give better tips!
I have seen the Healer/Companion and seawitch succubus builds on the wiki and they do seem fun to try at some point
A part of the inspiration for this build idea I had was seeing hunter build at the bottom of the spellcaster wiki
Deepone seems like it could go well with this guerilla warfare succubus build my only issue (as dumb as it may sound) deepone Lona is too clean for what I'm picturing
Ideally I was thinking moot for the race since the stats and feel align well and the deepone transformation that clears all dirt and summons sirens doesn't fit the theme I was thinking of
By the end of the game I want to imagine the people of the island talking about Lona as if she was mythical beast stalking the forest hunting down and violating poor defenseless men
