Changes

[[Image:runeskill.jpg|thumb|Rune Socket]]Skill Runes in Diablo III improve a character's active skills in various creative ways. Runes don't just add damage; they modify the skill in some way, making it more powerful and fun to use, as well as allowing for character customization. Runes can be used very strategically; different runes in the same spell will do things. For example, the Wizard skill Blizzard would gain different benefits from different runes. A few hypothetical Blizzard bonuses: more falling projectiles, longer duration, more damage per projectile, longer chill time, better to/hit, better chance of critical hit, and so forth. Also, each of those types of bonuses would be increased in power by the quality of the rune used, allowing for a huge variety of potential bonuses and play styles.
