General trapping guide

Overview
This guide discusses rangers specialized in using traps to overcome their enemy. Traps are a powerful weapon when used correctly, but in unexperienced hands they turn against their user. This guide is intended as a starting guide for new trappers, but it includes more detailed information and tips for more experienced trappers.

Wilderness Survival
Wilderness Survival is the most important of the attributes of a trapper. All of the traps in the game, excluding Viper's Nest, use Wilderness Survival. Therefor the trapper should have the maximum possible WS, currently 16. (12 + 1 from mask + 3 from a superior rune) This increses the damage output of the traps and the duration of secondary effects such as blind, cripple and bleeding. It also increases lasting time of many Nature Rituals.

Expertise
Expertise is also very important for trappers. It lowers the huge energy costs of the traps so that the trapper is able to set many more traps than he normally could. A trapper should have a very high expertise rank, preferably 12 or 13.

Beast Mastery
Beast Mastery is not always needed, but the trap Viper's Nest and some Nature Rituals benefit from it. If you use BM based skills you should usually have rank 6 in it.

Secondary attributes
Depending on the task at hand the trapper might want to use skills from a secondary profession or the Marksmanship attribute. The trapper will generally have only a few attribute points to spend on these skills and he should never spend the points to more than one secondary attribute.
