Scion of Elemental Earth (Wisdom)

You’ve been exposed to the primordial magic of the Elemental Plane of Air, granting you the following benefits:

Elemental Magic. You learn the druidcraft cantrip, using Wisdom as the spellcasting ability.

Earthen Shield: You can use a bonus action to conjure a bulwark of earth that provides half cover to you or a creature of your choice within 30 feet of yourself. The bulwark remains until the start of your next turn. You can create this bulwark a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest.
