Infinite Respawn Very Fast XP (All Classes But Hunter Preferred) (Patreon)

Forgemaster Garfrost is located next to six adds in the Pit Of Saron (70-80) dungeon, the adds are named Wrathbone Siegesmiths. These mobs have very low HP for their level and offer decent xp, I was getting around 3000XP in the late seventies for killing all of them. It is possible for an appropriate level player to kill them quite quickly with decent gear. 

These mobs respawn if you drop combat with the boss. You can run a short distance away from Garfrost to drop combat, which leaves you with a quite good, but not great, xp grinding opportunity. 

For Hunters, this is a very good situation. As I've covered in previous posts, Hunters can drop combat almost instantly with the item:  

Pet Training Manual: Play Dead 

alternating with the hunter's own feign death ability. 

This technique is faster than any known solo technique for a level-appropriate hunter, even including method zero.
