At first I was overwhelmed with the enemies because I wasn't focused and was caught off-guard . But I handled the situation pretty well and almost survived the assault.
The thing I don't understand is my teleportation rune didn't work. And I made a foolish mistake thinking it didn't work because of my "last stand" talent (which disables movement) that was active and I turned that talent off decreasing my hitpoints drastically and tried to teleport away But still I couldn't teleport!! The teleport rune just went on cooldown and nothing happened. And then I died horribly against those few remaining archer orcs

The thing I want to learn is what caused my inability to use the teleport rune. I looked at the log. And It just said my charcter uses the teleportation rune and continued with the damage reports without saying if and why it failed. Does anybody have an idea why this could happen?
PS: I think there can be pop-up message saying that the teleportation failed because of this and this reason. Or It can just be written in the logs.
