Living Blade
Prerequisite: 1 Essence sacrificed + Pact of the Blade feature & 6th level
When you summon your Pact Weapon, select a damage type: until you take a long rest, your Pact Weapon deals this type of damage. Once per turn, upon scoring a hit, the bonded weapon will also evince an effect equal to Prestidigitation. At 9th level, the blade is empowered by souls. For each enemy the greater servant slays in combat personally they may add to their soul count. If it was by death blow they add 2, if by doing the majority of damage they add 3. When they strike a target, they may channel this into their damage on a 1:1 basis, up to a maximum at once equal to their Sanity. Strike killing blow for blood/souls to work
