Thunder's Fang

You create a dagger shaped using red lightning and fling it at a target within range. Make a ranged spell attack against the target. On a hit, the target takes 1d10 piercing damage. Hit or miss, the shard then explodes giving paralysis to all in zone for one turn. The target and each creature within 3 feet of it must succeed on a Dexterity saving throw or take 2d6 lightning damage.

At Higher Levels. When you cast this spell using a spell slot of 3nd level or higher, the lightning damage increases by 1d8 for each slot level above 1st.
