Blinding Flash

A creature within range is subjected to a blinding flash before its eyes. The target must make a Dexterity saving throw. If the target succeeds (DC15) nothing happens. If the target fails it is blinded for the duration of 1 minute or 2 rounds in combat. 

At the end of each of its turns, a blinded target can make a new Dexterity saving throw, ending the blindness on a succes (DC15). It cannot make this saving throw if it is stunned or otherwise incapacitated. 

At Higher Levels. When you cast this spell using a spell slot of 2th level or higher, the number of targets equals the spell level.
