so how does the tentacle room in complexbreeding work exactly, i read that it drains essence from slaves so i tried using it but it doesn't do anything, did i install the mod wrong or do you need to do something else to the slaves to make them lose their essence?
Drains them very slowly. It has low %, but you must have unlocked Dwarf girl that gives you option to upgrade specific rooms. And upgrades are random.
Keep in mind that you accumulate drained essence, that you can spend on increasing tits and pregnancy births or adding certain essences. Example. In upgrade menu thing called 'TAINT' -10 is adding 1 essence of eternal
Vitality Storage is accumulated essences from drained stuff. You can drain everything.
Enlarge Breast Size -4 means -> It takes 4 points from vitality storage to increase breast size.
Enlarge womb size -8 means -> It takes 8 points from vitality storage.
Drained sacred essence +2 -> It gives 2 points to vitality storage for 1 sacred essence from creature.
If a creature doesn't have that particular essence it does nothing.
And it is low %, meaning you will wait a long time until women is fully drained or otherwise.
