Searched various keywords in the forum for this, and did not find any threads relevant to this technique.
This trick may not be an 'amg exploitz' but I found it to be amazing and decided to share it with you guys.
Picked up cooking recently and I started the quest
Dig Rat Stew - Quest - World of Warcraft
I went down to the area where the dig rats spawned, and began to kill them for the quest (I wanted the recipe)
The objective is to kill dig rats,
Dig Rat - NPC - World of Warcraft
while killing them, they have a chance to drop
Unconscious Dig Rat - Item - World of Warcraft
Here's the exploit: Save them. They have a decent drop rate and I managed to farm up about 30 of them in an hour after getting a nice path down to farm them.
/target [nodead] Dig Rat
Using this macro you'll find them easier.
They can be summoned anywhere. They summon a level 1 critter that can be killed.
They also have no cooldown, so you can summon a few of them before a boss fight, and start the fight with full rage.
Note: They cannot be used in the arena.
Thanks for reading.
