Augary Rock Mission - Doppelganger

Hey guys! Let's throw all ways to destroy your Doppelganger here.

Here's what I found that works so far:

Ranger (primary or secondary, especially if you're a monk or a tank)
Load up a max leveled pet or as close to max level as possible and then load up as many skills as you can relating to Beast Mastry. Your Doppelganger is unable to produce a pet since it only is able to produce a copy of yourself, rendering all skills related to Beast Mastry completely worthless to it. Do not load Troll Ungent to prevent the Doppelganger from healing. Remember, NO HEALING SKILLS ALLOWED IN THIS ONE. Load one skill which will allow your arrows to do damage. Your Doppelganger will either concentrate on trying to kill you or will concentrate on killing your pet. Either way, you will successfully take away life from it.

Monk
Due to the difficult nature of smiting spells and the fact that even if you're running away from it, you'll still get hit by them, my best recommendation is to rely on your secondary profession but TRY to get to Senji's Corner in Factions and change your secondary to Ranger and use the suggested tactic above.
