So this isn’t new per se. But here it is!
A wand that does basic wand damage(minimum damage like the noobie wand), and when you draw, members in your party can see your drawing. The purpose of this wand is to educate new rune mages. I find myself constantly teaching and video-sharing on discord to teach mages. An in game mechanic would be really useful.
Any wand design will do, even the noobie starting wand, assuming you allow it to be transmogged (perfecto!).
Can either make this wand tied to an achievement or just sell it to anyone. Hell, make it a tinker item. I’d craft one. Just gimme!
