Funeral Pyre

The dead do not fear the flame, for within its embrace they may return to the light. The living, however, often feel differently.

You call forth spikes of burning wood from the ground around a target of your choosing within range, attempting to trap them. The target must make a Dexterity saving throw. Creatures that are Huge or larger make this saving throw with advantage. If they fail, the target is impaled by the spikes and restrained until the start of your next turn, taking 2d8 fire damage and 3d8 piercing damage. If the target succeeds, they take half as much damage and are not restrained. The spikes fade into ash at the start of your next turn. If the target is slain by this spell, the spikes do not fade, but instead remain and become impossible to dispel.

At Higher Levels: When you cast this spell using a spell slot of 4th level or higher, the fire damage or the piercing damage (your choice) increases by 1d8 per slot level above 3rd
