Crowley's Crimson Elixir

You draw the blood of a willing target within range into a potion vial in your possession, creating a Crimson Elixir that lasts for 24 hours. The target takes 4d6 necrotic damage which cannot be reduced by resistances or immunities.

The target may drink this potion to gain its effects. Drinking the potion raises its hit point maximum by 2d6 for 1 hour. It also restores an equal number of hit points.

The Crimson Elixir has no effect when consumed by anyone other than the target of this spell.

At Higher Levels: Increase the damage taken by 2d6 and the healing by 1d6.
