Thistle Missile

You create three thistled and thorny bulbs and send them flying at targets within range.  You can send them at one creature or several.  Make a ranged spell attack for each bulb.  A bulb that hits does 1d10 piercing damage and that bulb sticks to that creature.  When a creature is hit and stuck by at least one bulb they need to make a constitution saving throw or become poisoned on a failed save.  When poisoned in this way the creature must make a constitution saving throw at the start of their next turn, if they fail this saving throw they become paralyzed while poisoned from this effect; on subsequent turns the creature may repeat this saving throw at the end of their turns, ending the paralyzed condition on a success.  Someone can take an action to remove a bulb from a creature within their reach, ending the poisoned condition if removing the last bulb from that creature.

At higher levels.  When you cast this spell using a spell slot of 4th level or higher, the spell creates 1 more bulb for each slot level above  3rd.
