SpoilerWoops! Probably had the wrong thread open by accident or didn't spoiler it, I'll edit that now. As for the cage we could either leave it, Grimms plan or maybe tie rope around the cage door and pull it from a distance? We don't really know what it is.
I'll roll knowledge nature now and then check if I've already rolled it, if so I'll edit this out....(1d20+13)[17]
:edit: I did roll it but I must have edited it in as the script failed.
