So, "All" and "Other" become your valid targets when sheathing or unsheating, and I understand that, at least as a healer, this is useful to know as it allowed you to target players outside of your party with cure, protect, stoneskin etc.
I'm not completely understanding of the system though; as in I'm sure there's some info I'm missing out on that I wouldn't know specifically to look for-
Can someone blast me with info that could be potentially helpful? It'd be greatly appreciated.
