maybe some "other" way to capture people than cagetraps, to later corrupt or use for other things.
maybe some sort of combat "spell/ability" that places the victim in a cage if successful? so they can be transported then (maybe some sort of "lust" magic material so it doesnt spawn a million cages with value out of nowhere... think warlocks have blocks that disappear after a while? maybe the lust cage just disappears if noone is in it anymore and cant be used to build cagetraps etc. or maybe just disappears after a season setting people inside free again if not transfered to a cell or other cage? *shrugs*)
or a very low % chance to "seduce cage" with these abilities:
Learn the secret of lust: The succubus becomes a courtesan and receive access to several interactions that affect intelligent creatures. Her enemies will have a trouble raising a sword at her. At regular intervals she will become lusty and will multiply both her and other succubi's abilities.
or
Learn abyssal gaze (lust): Render an enemy unable to think straight, they may even fall unconscious after a while.
or maybe the whole lust/corruption side could be some attacks that level up somehow based on a skill or training... (like dwarf mages learn more spells? or as own "corruption" skill that levels up by seducing in combat, going out to villages, corrupting/torturing prisoners? temples? dream interfering?) and at different skill/levels lust/corruption related attacks get stronger/ or get more effects.
as example:
maybe first combat seduction just stuns enemies, then prevents attacks against the succubus (secret of lust), then puts people to sleep (abyssal gaze), then turns them berserk to protect the succubus and turns them on their friends (like "Sow discord (envy)") and later has a chance to just capture them in a cage. (maybe if they survive the berserk part they calm down and are caged/captured then?)
or these could be random chances to apply instead of their own spell, but i guess that would be "the secret of lust" then with a few random outcomes if used in combat then. would probably be better to combine it with "the secret of lust" then just as random chance to do x or y or z. (stun, sleep, calm, berserk, cage) so a level 1 corruption would i.e. have 10% chance to stun. a level 2 would have 10% chance to stun or 5% to set to sleep. and level 5 might randomly cause be 10% stun, 5% sleep, 5% calm, 10% berserk, 10% cage on skill attacks or so.
hmm isnt the sorcery (?) skill used anyways for temples? might could double as level for seduction/lust/corruption based skills/attacks or so.
i think i once read somewhere in here the idea of going out to villages/dreams and seduce/corrupt people there to bring them back... something like some of the other playable races have to get slaves or items. (orcs have dreamwalking and raiders. and warlocks have prisoners and also raids)
well just a random idea for "something else than cagetrap capturing".
its probably just me who doesnt really want to use cagetraps
(i probably need to use the temples more in general... the last forts always ended up in a tantrum after a siege haha. dunno why... maybe from dead pets or so... *shrugs* (well currently trying out the orks))
Just my thing on the children:
Incubi (in mythology) would use succubi to steal *stuff* from men and impregnate women to... create new succubi I believe? So, how about "infecting" prisoners to create young succubi?
i guess the problem with impregnating is... time... waiting 10+ years for a child to grow up to be a normal citizen just doesnt really work that well with DF.
i would say corrupting does work kinda well there... with low corruption turning prisoners into race based ... demon-y thingies.
and maybe with new higher more "time and magic" consuming methods that maybe turn humans/elves slowly into full succubi. maybe over a year you need to assign (maybe "opposite gender" succubi) at a temple near prisoners to slowly corrupt them? maybe the highcorruption ritual randomly adds "corruption liquid" on one bodypart/limb of a random prisoner nearby (similar to how you can be covered in water/blood) and you can just add one more layer of corruption on someone who hasnt got corrupted last 4 weeks or so. and once the whole body/limbs are covered it switches to a normal succubus.
or it could even be something like a mutation/illness. (no bloody idea if that would work mechanic wise... but might be more elegant than water covering mechanics.) and the "high"corruption ritual could affect nearby prisoners with an illness... and the more you do the ritual the worse get the illness and they slowly mutate limbs and horns etc at higher levels until they totally switch to a succubus at max "illness". and if you dont corrupt them regulary the illness gets weaker... so you have to corrupt the prisoners you want to corrupt to succubi every season or so.
but that probably should be rather time/material/labor consuming so its more a rare thing to do.
well just random ideas.
