Guide for Magic Resistance in Aion
You need to change your magic resistance rate when your level (aion gold) up. The rate of magic resistance occurrence is greatly decreased if the attacker level higher than the defender level in game.
We know that the mr rate is base upon on how much higher then the mr which is over the attacker’s ma in Aion. So it will be no resist between 2 level 50's fighting such as a mr cleric with 1800mr against a mage with only a ma of 1200.
You will gain more mr depends your level but being the statement saids the mr rate, it is not the amount of ones mr, has changed according to level. Lowie can not attack a higher level character from the natural magic resist rate gained from being higher right now.
