Breath of the Desert Dragon

A gust of warm air lifts creatures skyward. You create a 15ft burst up too 50ft away. Each target in the burst can fly 30ft + your DEX modifier as an immediate reaction. Until the end of your next turn, each target can fly the same distance equal to there walking movement. If still in the air when the spell is finished, they will take 1D6 damage for every 10 feet it fell. The creature lands prone, unless it avoids taking damage from the fall
