Chaos Fire Whip

This spell is from the Dark Souls spell collection.

You create a whip made of churning lava and flames that strikes at one creature of your choice that you can see within range. The target must succeed on a Strength saving throw or be pulled up to 10 feet in a straight line toward you and take 2d8 fire damage.

Whether the target succeeds or fails, the 5-foot floor area originally occupied by the target and all 5-foot areas passed through by the target as a result of this spell become covered in lava. The lava lasts until the start of your next turn and any creature that starts its turn in the lava takes 4d8 fire damage. The lava damages objects in the area and ignites flammable objects that aren’t being worn or carried.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the lava lasts for an additional round for each slot level above 4th.
