Class Mechanic - Mark
As a tank class, Guardian Fighters are well-versed in the ways of drawing aggro. With your Class Mechanic, you can Mark any target to "challenge" them. The challenged foe will have lowered Damage Resistance, and you build twice as much threat when striking them. Whoever you have most recently marked is considered your Mark Focus.
Previously marked targets lose your focus, and if they damage you, Mark will be removed from them. Guarded attacks will not remove your Mark.
At level 30, all adventurers must choose which of the two paths they will follow to continue their adventures. Each path represents a different way of playing the chosen class, so choose wisely.
