Tectonic Carapice

Earth and rock coalesce around you, creating an earthen suit of armor. You gain 50 temporary hit points. While you have these hit points, your speed is halved and you have disadvantage on Dexterity saving throws. If any of these hit points remain when the spell ends, they are lost. While you have these hit points you gain the following benefits:

• Your AC can't be lower than 20
• You gain resistance to nonmagical bludgeoning, piercing, and slashing
• You can’t be forcibly moved.
