Bone spike

You hurl a bone spike out of your palm towards an enemy within 30ft, make a ranged spell attack against the target.
On a hit the target takes 1d6 + wisdom piercing damage and will take 1d4 slashing damage at the end of each of its turns for 1d4 or until concentration is broken or the spike is taken out by spending a bonus action.
creatures who are tiny in size can be pinned to walls or the ground when hit. This spell’s damage increases by 1d6 when you reach 5th level (2d6) and the amount of turns the spike stays in to 1d6 rounds, 11th level (3d6 and 1d8), and 17th level (4d6 and 1d10).
