Certain to be activated
Endures the damage down upon 6 characters of the same race in a certain area once and the suffered damage will form a defensive shield. Light Shield: Absorbs some long-ranged physical and magical damage.
When a shield is used in the Abyss, the Mine Shield is certain to be activated. As to Spirit Wall of Protection, it seems a good skill for fleeing or launching special attacks when the caster is besieged by more than one opponent, but it cannot be used together with LOTR Gold. However, if it is used following Warmer, the caster will benefit.
