While looking through a guide elsewhere, I noticed that you can attach combat runes normally used by other characters to equipment with open sockets. What sort of effect would that have? I can't imagine it would allow my character to use other classes' combat arts but the guide didn't mention any specific details.

Ah, I remember seeing those extra bonuses on runes but didn't know just what they meant. Thanks.

I love taking the Demoness runes when playing my Dwarf and socketing them on my rifles and back cannon. I never stop seeing life flowing into me when I use Flamethrower + a good rifle.
