A Trapper is a Ranger focusing on Trap skills and other skills which enhance the usage of traps.

The attributes mostly used on trappers are Wilderness Survival, Expertise and Beast Mastery.
Trappers are very popular in the missions "Zaishen elite" and "Zaishen Challenge" where the enemy will approach players, so many traps can be set around the players' start base.
Trappers often use Echo chaining in order to get 3 of the same trap.
The skill of a trapper involves being able to aggro a mob in such a way that they become forced into the traps, and if needed keeping them there long enough so that the traps damage them at their full duration. In some cases spirits are placed near the traps to draw aggro.
