1 minute/mana
As an action, you lift three small to medium rocks or similar earthen objects within 2 meters, causing them to float around you. Until the spell ends, the rocks move with you, shifting position. You can dismiss the rocks on your turn (no action required).
Each time a creature targets you with an attack during the spell’s duration, roll 2d10 to determine whether the attack instead targets one of your rocks.
If you have three rocks, you must roll a 9 or higher to change the attack’s target to a rock. With two rocks, you must roll an 10 or higher. With one rock, you must roll an 11 or higher. A rock’s Defense equals 11 + half your Aptitude Bonus (min 1) + your Dexterity. If an attack hits a rock, the rock is destroyed.
A rock can be destroyed only by an attack that hits it. It ignores all other damage and effects. The spell ends when all three rocks are destroyed.
Augment
Orbital Defense. You can expend 1 additional mana to cast the spell as a reaction, which you use when you are hit by an attack or missed by 4 or less.
