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