You create five swirling, purple orbs of arcane fire. Each orb hits a creature of your choice that you can see within range. An orb deals 1d8 + 1 fire damage to its target. The orbs all strike simultaneously, and you can direct them to hit one creature or several.
If a target fails a Constitution check, it is subsequently put on fire for three turns. Every turn, it suffers an additional 1d6+1 fire damage. If a burning target stands 5 feet or less away from another enemy, that enemy too must make a Constitution check and risk being put on fire as well.
At Higher Levels: When you cast this spell using a spell slot of 4th level or higher, you create one additional orb for each slot level above 3rd.
