Infusion Ring

The Infusion Ring skill (for mystic) is somewhat poorly described in the game. According to the Gameforge Tera forums, it is the counterpart to the Corruption Ring skill, but it doesn't technically exist. Once the Corruption Ring skill is used, the Infusion Ring will automatically trigger and release MP to the caster (and possibly, other members of the party?). A variant use is to activate the glyph which reduces damage taken by 50%- it becomes a last resort when the caster is about to get one-shotted.
