Question bout a rune

I have a warrior rune of minor absorbtion. if i put it on my elementalist ( if i can) will i reduce the dmg i take from enemies or is it just for warriors

Warriors only!

LOL... Runes are professions specific. If they don't pertain to your profession(s) then no, you can't benefit from them

I'm a W/N, does this mean I can put Necro runes on? Cause I've tried and it seems it can't be done

if the rune benefits your armor, it is specific to your primary quest. otherwise it would be a rune of vigor which any armor could use.

I wouldn't see why it wouldn't "work". What's not working?

The icon has a red cross on it when I hover it over the item I want to rune

No, you can only put necro runes in NECRO armor. Warrior runes for warrior armor.

Thanks for clearing that up.
