To spare any more questions or complaints on the matter:
Runes upon blades strike the flesh of their target and thus are deliberately designed to bypass blindness. This is a long-standing bug that has now been fixed.
I would strongly suggest re-evaluating whether fighting Loremasters blind is a wise idea and - should you come to the reasonable conclusion that numerous (quieter) people have arrived at, you will find that your eyes (and consequently my ears) are far less frequently disturbed.
In the land of the blind, the one-eyed man is king!
