The generic “Hit something with a polearm” active skill. This skill is similar to pound, slash, and stab. One of the few melee skills that can be used from behind another tank, not that anyone ever does this.
The in game help reads:
Skill duration: 1+(random)/24. Type of skill : offensive skill. Party rows : 1st and 2nd. Affecting stats: Str/Dex. It uses 32 endurance points. Anyone who uses polearms, from pikes to tridents, know that it is to their advantage to keep their enemy at a distance and to thrust at them as they try to close. If done correctly, one can safely from a distance, and strike their foe from one side and push the haft of their weapon so the business end comes out the other side. Enemies are much easier to deal with when they are lifted up off the ground on a eight foot spear placed right through their midsection.
