There's bounded fields around the forest to detect movement if nothing else. The red girl called Lana just blocked the blow at the last second. She got lucky. If you really want me to call it a GM fiat so be it I didn't do it to insult you, or archer. I'm not even trying to keep her where she is with the cursed trees like I could. She hit the trunk but didn't do much about the roots that were attacking it, nor in the first place should she have been able to actually hear the challenge as I didn't intend it to be that loud in the first place, nor would his smell be that easy to figure out given he's nearby some chimera most of which have wounds due to Anderson ontop of the nearby skeleton army, and Rider approaching nearby.
