A Large or larger Monstrosity with a challenge rating of 10 or less (chosen by the DM) appears in an unoccupied space within 15 feet of you. The creature is hostile toward you and attacks immediately. The creature disappears when it is killed or when you are reduced to 0 hit points. If there isn't enough space for a Large or larger creature to appear, this card has no effect.
