Rating
Rating is a modifier to incoming and outgoing damage, healing, mana consumption, mana charging, and aetheria surging.
For Example:
The formula for Damage Rating is: (100 + <total damage rating>)/100
Because of this formula, each point in damage rating is equal to a 1% increase in damage.
So, if you have 10 Damage Rating, (100 +10)/100 = 1.1 (or a 10% increase)
Multiply that by the amount of damage you do to see the damage modifier in action.
Taking this into account, if you do 100 damage, it would change to 110 damage. (100 * 1.1 = 110)
Note: Damage output in game already reflects the modifier.
Listed below are all known types of rating, and the ways to increase/decrease them.
