Dart Plant

You summon a medium, poison-spitting plant at a point you can see within range. The plant has an AC of 11 and 15 hit points. At the end of each of your turns, the plant fires at the closest hostile creature. Make a ranged spell attack against the target. On a hit, the creature takes 2d8 poison damage.

When you cast this spell using a spell slot of a level above 2nd, the plant may make a number of attacks equal to half the slot's level rounded down. In addition, the plant's  HP increases by 5 per slot level above 2nd.
