Blazeflash

You create an instantaneous flash of embers and ash that fills a 15-foot cube, centred on a point that you can see within range. Each creature in the area must make a Constitution saving throw. On a failed saving throw, a creature takes 3d4 fire damage, and is blinded until the end of your next turn. On a successful saving throw, a creature takes half as much damage and isn’t blinded.

At Higher Levels. When you cast this spell using a 2nd level spell slot or higher, the damage increases by 2d4 for each slot level above 1st.
