As an action, you can create a vial of viscous crimson liquid that smells and tastes foul. A creature can drink the contents as an action. When the oil is drunk—and at the start each of the creature’s turns thereafter—it regains 3d4 health.
If the creature is able to regenerate, it does not become wounded or incapacitated as a result of regaining health.
If the creature takes acid or fire damage, this healing doesn’t function at the start of the creature’s next turn.
You can increase the healing by 2d4 for each additional catalyst expended.
