Diablo III Runestone System Revealed
The Runestone system has been posted on the official Diablo III site: http://us.blizzard.com/diablo3/world/systems/runestones.xml
The five runestone types are Crimson, Indigo, Obsidian, Golden, and Alabaster. They can be used to modify your active skills. Each runestone has a different effect on each skill. For example, adding a Crimson Runestone to a skill may enhance its damage, while adding an Alabaster Runestone might add a stun effect.
Each runestone also comes in different ranks of power, with the higher ranks having more dramatic results. There are a total of 7 ranks.
Some examples of how each runestone affects certain skills was revealed on the Diablo III site, but most will have to be discovered in game by experimenting.

Some of the menu UI has also been shown. The image shows how to add runestones to skills, but also reveals the look of the menu and its tabbed interface.
We know that all the systems will be revealed before the beta launches, but we don’t know how many more systems are left. Here’s hoping to frequent updates!
