I don't know if it's WAI or not but when the Bone trap proc the champion can disangage without any problems: - Champ A step right in front of the trap - Trap procs and the Spooky Skeleton engage Champ A giving it Fear - Champ A moves on another square as if it's not engaged
If that's happening, then it's definitely not WAI, unless the champion has mobility or something that stops it from engaging. I think I remember this happening to me.
