Winged Shield

A shining barrier of magical force appears and protects you. Until the end of your next turn, you have a +8 bonus to AC, including against the triggering attack, and you take no damage from magic missile. In addition, you gain a flying speed of 30ft, and are able to disengage as a bonus action.
Recoil. If the Winged Shield manages to prevent the triggering attack, you are immediatelly disengaged and pushed back up to 15ft in the opposite direction of where the attack came from, gliding over any terrain and/or creatures in your path at a height of 10ft. If you are restrained, this ability has no effect.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, its duration is doubled for each slot level above 2nd.
