Touch is one of three ways to deliver a spell or power, the other two being Target and Self. This is a good delivery system for combat oriented mages, as it allows more accurate usage of spells and allows friendly fire to be avoided. These spells generally cost less in terms of magicka to cast then their ranged counterparts meaning a 10 Fire Damage spell with a Target property will cost more magicka than the exact same spell with a Touch property. In terms of spells per minute, touch can cast the most, allowing quicker level ups in magic. When creating magic, almost all effects can be made to be used via touch. Touch is best used with Destruction or Restoration spells as these spells require precision to be effective.
