Coin Railgun

You fling a coin at a creature using magic to boost it and grant it homing. Make a ranged spell attack against the target. The target takes 1d12+4 piercing damage. If you target a semi-weak object, it will be destroyed. The attack will never miss.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d8 for each slot level above 1st.
