I'm not even going to touch upon your "Counters"mallor wrote:
You're kinda missing the main point here, once in invis all that has no consequence, hence no "counter". Once in plain sight all those have an easy "counter" in form of consequence to your actions. So as there's resist to spells, or ways to see hidden people, there should be a similar way of seeing invis people, and I don't mean killing a huge ass NPC with 0.0001% drop of an item you then need to wear to be able to see invis, and don't even get me started on why minos can't wear MASKS. So it can be a skill or spell/ability that does that, implementation details don't really matter. Maybe not as simple as eating a herb, but definitely not as hard as killing Vermi 1000 times.
No you're missing the point. You all believe that one mask is all there is, your ignorance is not an excuse for shouting "Nerf it!" or "Make it easy for me!"
