Flesh Alchemist

You carry with you a set of glass vials and extraction tools to condense the essence of a creature into liquid form. Over the course of one minute, you may extract the essence of a fresh corpse and add it to your collection. When imbibed, you gain the resistances and vulnerabilities that the creature had for one minute. When the vial is drenched over a weapon, give the weapon a damage type that creature was capable of using for one minute. Each vial has only one usage.
