Ooh, I really love this update! There is a bug in the farfields though: when using the Alchemist's pouch and a mageflare rune, the rune does not stay active for three digs, it only stays active for one. This is true in all of the zones (Underbark, Blightvein, Shimmera, Umbra, Void).
On another note, I love the fact that the mageflare rune isn't actually able to light up the whole area in the Umbra, really showing the power of that darkness. It also makes me wonder that the mageflare rune is just increases the light radius to >1000 for one dig (and turns the screen red)? If so, would it be difficlt to display the light radius of the active mageflare rune just for the dig during which it's active?
