Hello! Actually i'm levelling up my wereworlf perk tree, i almost finished it. 90% done, but if i want to stop being a werewolf and get into a vampire, all my perks earned by eating people will reset to 0?

The same works for the vampire perk tree?

M'aiq thinks your perk tree for either won't be reset.

I know that if you're a vampire lord then decide to get cured and later on become a vampire lord again, you will have all the perks you aquired earlier. I dont see why it wouldnt apply as a werewolf. Perhaps just save your game and try it? Worse case it doesnt work out then you still have your save from right before you did it.
