Arcane Spear

You hurl a spear of magical force at a target within range, forcing it to make a Dexterity saving throw. On a failed save, a creature takes 2d12 force damage and has its speed reduced to 0 until the end of its next turn. On a successful save, the creature takes half damage and its speed isn’t lowered.

At Higher Levels. When you cast this spell using a spell slot of 2nd-level or higher, the damage increases by 1d12 for each spell slot level above 1st.
