Don't bother with open world rare spawns. Fill up your group window and use Agents of Change. *need gold sub to use Agents of Change*. I was able to complete the Paladin Epic in less than 6 hours using them.
Tip: When crafting bog juice and edible goo, farm the beetle eyes and rat ears in North Qeynos instead of West Freeport. Also, Make sure you have food and water before you craft them. Otherwise you will consume them.
Tip: When doing the Plane of Sky portion, buy the EFREETI Key from the Key Master. Many posts called it Veeshan's Key which is confusing. Put the Efreeti key on your cursor and click the northern pad to gain access to the quest room.
I used Bonzz.com for most of the Paladin Epic. Google Bonzz paladin epic 1.0.
