Prerequisites: The ability to cast at least one spell from the stone theme

You can harness the magical power of stone for your protection. When you expend mana to cast a spell, you can simultaneously use a strand of the spell’s magic to create an aegis on yourself that lasts until you finish a long rest. The aegis has health equal to your level + your spellcasting ability. Whenever you take bludgeoning, piercing, or slashing damage, the aegis takes the damage instead. If this damage reduces the aegis to 0 health, you take any remaining damage.

While the aegis has 0 health, it can’t absorb damage, but its magic remains. Whenever you expend mana to cast a spell, the aegis regains an amount of health equal to the mana you expended.

You can move the aegis to another creature that you can touch or see within 9 meters as a bonus action.

Once you create the aegis, you can’t create it again until you finish a long rest.
