The current one is too large for some styles/builds. One reusing the aethereal well, but changing the glow to red, would be welcome. Or, something abt that size.
In the vampire “bastion” house I placed a platform under the well and together with platform pushed it beneath the floor, until only small part is sticking out and it worked (i guess game checks where its placed on something or just “levitates”)
If it's for aesthetics this won't help you, but for functionality you can switch to an armory slot that doesn't have vampirism saved on it, then switch back to your vampirism armory slot to instantly get back down to level one vampirism.
Maybe an all in 1 "well of lamae bal" that can up or lower your level
Even if it only did the effect of the basin jtt could be a statue of her or whatever as long as it isn't swimming pool sizes
There are people who want to increase their vampirism level? I only do it when I want to feed for roleplay reasons, then I have to get my level back down so my character isn't useless.
