@FYZdnt from the sounds of things, they need to periodically feed on "energy and mana", so it wouldn't be a one off thing, it'd be the whole tribe probably once every couple days, possibly daily...no matter how much one might enjoy the process or how little they'd suffer from being repeatedly drained like that, that'd take a LOT of effort for one man to keep up over time
building a shop where they can continue to do as they always did by spreading out the drain across a willing male group was by far the better option. if you want to berate him over something, get mad at him for not keeping one or two of the best looking ones around when it inevitably turns out he sends them all away (after all, one or two a day should be a lot more manageable than the whole damn tribe)
