Dazzle (Erasmus' Razzle Dazzle)

You can blind all foes within 15 feet of you. All creatures that you can see within range, and that are also facing towards you, have to make a Constitution saving throw. If it fails, the target is blinded or for the duration. At the end of each of its turns, the target can make a Constitution saving throw. On a success, the spell ends.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, your range extends an extra five feet and lasts one extra round for each slot level above 2nd.
