Dark Reign - Goblin Dojo
This is one of the easiest most annoying tasks you'll have to complete for your DoN progression. It's so easy because you'll never be fighting more than a few mobs at a time. It's so annoying because you have to wait a total of 20 minutes or so during the entire task since it is designed for level 70s and gives them time to kill/med.
There are numerous waves of goblins that you'll have to fight. Your main purpose is to quickly dispatch of them all until you finally fight the Storm Reach Sensei. He's just as easy as the other ones (though if you're 100 he does con green, *gasp*). Kill him and loot what you need. After you're done return to the Dark Reign camp and turn it in for a character flag.
Note: If you're playing on Phinigel as you can tell this guide is written for players wayyy beyond your current expansion. If you'd like please leave comments below for players YOUR level and I will add them to the guide - thanks in advance for anyone who actually does!!
