Mana Shield

Mana Shield is an utility spell, and applies buff to a friendly target that gives a small amount of damage reduction.

The damage reduction gained from mana shield depends on the armor type the target is wearing (needs verification):
 * Cloth: 3%
 * Leather: 5%
 * Plate: 8%

Shortcuts
Mana Shield is a very forgiving spell, to the point where almost any spell can turn into Mana Shield on accident.
