Entropic Burst

You shout and point at a place within range; magic swells through you and arcs out to that point, creating a 5-foot radius sphere of explosive magic. Each creature within the radius makes a Dexterity saving throw or takes 1d6 of either fire, lightning, cold or acid damage (your choice).

At Higher Levels: This damage increases by 1d6 when you reach level 5 (2d6) level 11 (3d6) and level 17 (4d6)
