1st-Level Transmutation
Casting Time: 1 action
Range: Touch
Components: VSM (a sprig of mistletoe)
Duration: Instantaneous

Up to ten berries appear in your hand and are infused with magic for the duration. A creature can use its action to eat one berry. Eating a berry restores 1 hit point, and the berry provides enough nourishment to sustain a creature for one day. However, if a creature eats more than five berries in 1 hour, it must succeed on a DC 12 Constitution saving throw or be poisoned for 1d4 hours.
The berries lose their potency if they have not been consumed within 24 hours of the casting of this spell.
At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the first time a creature eats one of the berries created by this spell, it restores 1 additional hit point for each spell level above 1st.
