Grist Cakes
Wondrous Item, Common

These rations made of troll meat slowly regenerate, promising a long-lasting food supply. A creature can use a Magic action to eat one cake. Eating a cake restores 1 Hit Point, and the cake provides enough nourishment to sustain a creature for one day.

A pack contains a maximum of 10 cakes. So long as at least 1 cake remains uneaten and unspoiled, the pack regenerates 1d6 cakes per day. If you take Fire or Acid damage while carrying a pack of Grist Cakes, 1d4 cakes permanently spoil and will no longer regenerate.
