Betterberry

You gain a healing pool equal to 10+ Your Spellcasting Modifier. You can split this healing among berries, which are created in this spell. Each berry must have at least 1 Hit Point of Healing in it, and the created berries provide enough nourishment to sustain a creature for one day.

You can spend a bonus action to eat one berry, or spend an action to eat up to 4 at a time. 

Uneaten berries disappear when the spell ends.
