Utility

From WoWWiki

Utility is the term for a spell or ability that has some special effect that is helpful, but usually not directly combat-oriented. There are exceptions: some combat spells with especially odd effects are referred to as utility spells. Utility spells are sometimes also categorized as buffs when the effect is helpful, and only castable on your allies.

Examples:

• Druid: Teleport: Moonglade
• Mage: Amplify Magic, Dampen Magic, Conjure Food, Slow Fall, Teleport, Portal
• Priest: Levitate, Mind Vision
• Rogue: Lockpicking
• Warlock: Unending Breath
• Shaman: Far Sight
• Hunter: Misdirection
