Diablo 3's missing runestones found at GDC
If you've followed Diablo 3's development for a long time, you might remember the idea of Runestones. They were meant to be actual in-game items that could supplement character abilities in various ways, such as adding a fire attack to a melee hit, or doubling the power of a spell for free. When the game arrived last year, the Runestone system was nowhere to be seen, replaced by the controversial Skill Rune system. So where did those Runestones go? Diablo 3's technical designer Wyatt Cheng said during a talk at GDC that they're still around, in one form or another.
The Runestone system was originally created to add flexibility to character skills, and to give players a chance to experiment and play around with new abilities after they had gained them through leveling up. The original idea had ten different effects that could be added to various abilities, including striking, lethality, efficiency, life-stealing, poison, slowing and so on. But ten was too many, Blizzard decided, and they opted to boil them down into five different stone types (Crimson, Obsidian, Indigo, Golden and Alabaster) that would each affect skills in a few different ways.
Cheng said having actual stones in the inventory worked in a few different ways. It gave the system a sense of discovery, as players enjoyed seeing which stones granted certain effects, and it accomplished the original goal of allowing players to experiment with customization. Managing the stones in the game's inventory was a "nightmare," according to Cheng, and player expectations didn't always match what the stones actually provided.
In the end, the team went with the existing Skill Rune system, which allowed Blizzard to give specific skill and stone combinations more "flavorful names," and let the team make sure that the added effects were appropriate for the skills they matched. But Cheng said the effects were still in there: Some runes still slow opponents or add more damage to attacks, and those were the effects originally conferred by the stones of Indigo and Crimson.
