Dazzle

You throw open your hand and release a disorienting spray of glittering color motes. Each creature in a 20-foot cone perceives your space as heavily obscured and must make a Constitution saving throw. On a failure, it is blinded and its speed is halved. The spell ends at the end of your next turn.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the cone’s size increases by 5 feet for each slot level above 1st.
