Deadened Emotions and Undead Aura - not good for making friends

You need to create the Draught of Reconfiguration which the recipe can be unlocked by reaching Vampire Lore lvl 14. It's a drink you mix, needs no Mixology skill to create it, and when it's created and you drink it, all the powers/weaknesses the vamp has are reset but you keep the points you spent on them so you can choose all the ones you want again.
