I thought I could use this spell to remove the runes you see when magical sight is activated, like the summoning runes.
But when I cast it on those runes, it does nothing but take away 5mana. Since they activate when you step on them and the creatures/constructs that appear are hostile, I thought they would also fit under "enemy rune" and restore 10 man. Is it only meant to work on runes, that an enemy caster has just casted?
It also says "remove" which I would interpret as getting rid of harmlessly without activating . I have only had the chance to test on my own runs, but when I do the rune activates, regardless if I cast the spell on the rune or myself.
Is this how the spell is supposed to work, or is it a bug? If this is not a bug, I think the description is misleading.
