Unsullied Blood (Moderate)
Activate ◆ envision
Blood offered from a willing donor was taken directly from the vein and stored in an ornate vial that keeps it as pure and red as the day it was extracted. When this catalyst is added to a Vampiric Feast spell of up to 5th level, instead of gaining temporary Hit Points based on the damage dealt, you recover half of the damage dealt as Hit Points. If the amount of Hit Points that would be restored by the spell exceeds your Hit Point maximum, you gain the excess as temporary Hit Points.
Traits
Items that have the catalyst trait are consumable material spell components that alter or magnify specific spells. Activating a catalyst is part of Casting the Spell. The catalyst might increase the number of actions required to Cast the Spell, as indicated in the catalyst's Activate entry. Additionally, the spell gains the manipulate trait if it didn't already. Because the catalyst becomes part of the spell, you can draw the catalyst as part of Casting the Spell.
An item with this trait can be used only once. Unless stated otherwise, it's destroyed after activation. Consumable items include alchemical items and magical consumables such as scrolls and talismans. When a character creates consumable items, they can make them in batches of four.
Something with the magical trait is imbued with magical energies not tied to a specific tradition of magic. Some items or effects are closely tied to a particular tradition of magic. In these cases, the item has the arcane, divine, occult, or primal trait instead of the magical trait. Any of these traits indicate that the item is magical.
