Ephorius' Flame Lance

You flourish the weapon as a massive serrated spear of fire appears rushing towards a creature in range. Make a ranged spell attack roll against a creature in range, on a hit it takes 3d10 fire damage and is paralyzed until the start of your next turn.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the fire damage increase by 2d10 for each slot level above 5th.
