Potion of Regeneration

When you drink this effervescent green liquid,
your body’s natural healing powers are radically
accelerated. You regain 1d8 hit points each round
at the start of your turn for 1 minute.
If you take acid or fire damage, you do not
regenerate at the start of your next turn.
If you are reduced to 0 hit points, you do not
regain hit points but have advantage on death
saves each round unless you take acid or fire
damage.
