Tank

A term that denotes a warrior. Warriors are called tanks because they have the highest armor level in the game and as such have the highest resistence to damage. Tanks can be one of two types:

Offensive Tank
A warrior specialized in heavy damage dealing. His/her primary focus is engaging the biggest threat in the enemy and quickly rendering it lifeless. His tools include knockdowns, bleeding and deep wounds. An Offensive Tank's biggest fear is hexes like Empathy that cause an attacker to lose health as well as negative conditions like Blindness that cause an attacker to miss.

Defensive Tank
A warrior fortified with all possible defensive tactics to soak up as much damage. A Defensive Tank will charge the enemy but will focus mostly on engaging the frontline of the enemy and keeping them busy fighting him/her. Defensive Tanks will use shields, stances and -if applicable- Protection Prayers to minimize damage inflicted upon them. They can take quite a long while to kill. Defensive Tanks can be used as booby traps using AoE spells that are centered on the caster such as Symbol of Wrath.
