How Do Runes Work


So I have been doing arena pet fighting for the major rune you can get from there although I am a little unsure as to how runes actually work. I cant seem to find any information either.

Do they need to slot into other equipment items similar to gems? or do the have a special bar to slot into like AA feats?


You only have to click it and you have a short cast, then you can see it on top of your screen.
You don’t put them in any item or in your bar like AAs.
Some Runes have a 60 minute time of being active and others Will stay untill they get replaced by another rune of the same class/family. Mayor rune, minor rune and so on.
