Over the last couple of days I've briefly touched on Diablo III's new rune system, but after talking a bit with the game's lead can designer Jay Wilson for a bit I figured the system warranted it's own post. You see, while past games have featured items that augment the powers of your abilities, the massive scope of the rune system sets it apart.
The basics: As you play through Diablo III you will come across various runes, which can be slotted into active power slots to enhance their powers. Rather than just increasing the damage or range of an ability, however, the runes radically change the form and function of said abilities, almost creating completely new skills with completely different uses.
