A lush bunch of vegetable fronds suddenly springs from the ground in an unoccupied space you can see within range. As a bonus action, a creature can pull the fronds from the ground, revealing a root vegetable of your choice that has been grown in the shape of a blade. For the duration, a creature can use the vegetable blade as a melee weapon with which it is proficient. The blade deals 1d12 slashing damage on a hit (adding your ability modifier to the damage roll as normal), and it has the finesse property.   Additionally, on subsequent turns, the wielder or one of its allies can use a bonus action to take a bite out of the blade. Doing so heals the creature for a number of hit points equal to the blade’s damage die + your spellcasting ability modifier. Once a creature has taken a bite out of the blade, its damage die is reduced by one size—from a d12 to a d10, for example. If the blade is reduced beyond a d4, it is destroyed and the spell ends early.
