Very nice ranger build.

There are many variants of this build. But this is the one I use for now. All minor runes of course.

12 Wilderness Survival
10 Marksmanship
8 Expertise
11 Beast Mastery

Savage Shot, Troll Unguent, Charm Animal, Comfort Animal, Feral Lung, Poisonous Bite, Whirling Defense, Incendiary Arrows.

As I say, there are many variants. For instance, it would be adviceable to remove Whirling Defense against spell casters.

This does most of its damage through degeneratives such as burning, bleeding, and poison. In the end, it does a 14 health degeneration. It is also wonderful for interrupting, which is the main reason I like it
