Question first: do Runewarden have some kind of sense ability?
Idea next: This idea got denied for reasons I don't remember...but as a Shaman there are -zero- notification abilities. As Runewardens have skills that are specific to them, maybe a rune that notifies a Shaman whenever an enemy passes within 2-3 rooms of it (hell, I'd go for only that room for bashing purposes).
If a new rune is too hard to code, etc., then maybe a new skill (toggle-able[??wut]) that allows a Shaman to see when an enemy passes through a rune/room in which a rune of his or hers is sketched.
Reason, finally: I'm terrified of getting shat on while I bash, and putting this rune/any rune with the skill active at a bottleneck could alleviate some stress. Also allows for strategic positioning of runes to watch movements (nothing like seraph/daemon sense/watch).
On my phone, else I would expound how this could beneficial to all Shaman...not just me and my bashing fears.
Will expound with positive feedback
