As a reaction, which you take when you are hit by an attack that you can see, you can redirect attacks with gusts of air. Until the start of your next turn, including against the triggering attack, ranged weapon attacks have disadvantage against you and you have a +4 bonus to Defense against all other attacks.
You can expend 1 additional mana or psi to increase the bonus by 2.
You can expend 1 additional mana or psi to trigger the spell when a creature that you can see within 18 meters is attacked. The attacked creature gains the benefits instead.
