@jmucchiello Yes, the doll looks damaged. Whatever the opposite of a glass cannon is, this is what the doll is. It is hard to hit and hard to hurt but doesn't hit back really hard.
Dex save (with Disadvantage) +4=23 +4=16 The doll somehow makes it's save.
Break grapple attempt (with Disadvantage) +4=19 +4=6. I will presume that the escape attempt fails. @Kobold Stew it is your turn.
It's reached the point of being naughty word annoying. It's been 8 rounds. 8 round fights should be epic. This is not epic. I don't remember anything about what we doing before this fight started. I think we wanted to find somewhere to try a long rest. But this thing disappears and reappears so much I doubt we can assume anywhere is safe to rest.
