As an action, you can create a vial of liquid that smells like moldy cheese and has the texture of a troll’s skin. A creature can drink the contents as an action to stimulate its natural healing process. The creature regains 3d8 health immediately and regains additional health equal to half the amount healed by this effect at the end of its next turn.
You can increase the healing by 4d8 for each additional catalyst expended.
Major Regeneration. You can expend 2 additional catalyst to stimulate major natural healing. The creature regains the normal amount of health. The duration changes to 1 minute/catalyst and for the duration of the effect, the creature regains 5 health at the start of each of its turns (50 health each minute).
The creature’s severed body members (fingers, legs, tails, and so on), if any, are restored after 2 minutes. If the creature has the severed part and hold it to the stump, the effect instantaneously causes the limb to knit to the stump.
