==Rune Functions==

Runes have no function on their own, other than beautifying your inventory. They are only useful once they're [[socket]]ed in a skill, where they modify the skill's function, always in a beneficial way. Any rune in a skill is an improvement over the base function of the skill, and since runes are easy to swap in and out of skills, it's always in your best interest to stick a rune into a skill at the first opportunity.
