Dispel Flight

A specialized version of Dispel Magic that counters flying and flight like abilities. 

Choose one creature, object, or magical effect within range. Any spell of 4rd level or lower on the target ends. For each spell of 5th level or higher on the target, make an ability check using your spellcasting ability. The DC equals 9 + the spell's level. On a successful check, the spell ends.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, you automatically end the effects of a spell on the target if the spell's level is equal to or less than the level of 1+ the spell slot you used. So cast using a 4th level spells slot would dispel flight spell of 5th level or lower.
