Publisher's blurb: It's Time to Log In and Save the World! In the world of Infinity's Edge, the rarer a piece of equipment, the more likely it is to have Upgrades. And one of the more common Upgrade Slots any weapon, armor, or other item can have is a Runestone Slot. Runestones are versatile items that can add an incredible array of abilities to any item depending upon which one you slot into it. But be careful! Once a Runestone is attached to an item, you can't take it back out! This product contains 100 different Runestones that Infinity's Edge players might discover during their time spent adventurering in the virtual reality MMO Infinity's Edge, all based on their approximate level and the level of the gear thier quests grant them.
