[Guide] How to get the "Raiding with Leashes" Achievement

Raiding with Leashes - Achievement - World of Warcraft

You'll get the cat that stands inside Naxxramas from doing this achievement called Mr. Bigglesworth (Mr. Bigglesworth - Item - World of Warcraft).

To earn this achievement you are required to learn all the non-combat pets that drops from Molten Core, Naxxramas, Blackwing Lair and Temple of Ahn'Qiray. These pets have a decent droprate and I've gotten at least 1 pet each time I've done a whole raid. Molten Core, Blackwing Lair and Temple of Ahn'Qiray can be soloed but you'll need at least a few people for Naxxramas because of Patchwerk and maybe a few other bosses depending on your class/spec.

There drops 3 pets from each raid, you don't have to do the last boss in any of the raids but keep in mind that there is still a few hard bosses you need to kill to get access to the bosses that drops the pets. I suggest to take atleast 1 person with you when going to Temple of Ahn'Qiray and at least 2 persons to Naxxramas. For Ahn'Qiray you'll need a melee if you're a caster and a caster if you're melee to kill the Twin Emperors and for Naxx you'll need atleast 1 healer for Patchwerk since he hits really hard, it is doable as a blood dk but I suggest to take 2 persons with you as any other class/spec. Also a thing to keep in mind, you'll need frost damage to kill Viscidus in Temple of Ahn'Qiray. If you have no classes with frost spells in, you'll need either a Brunnhildar Harpoon, Brunnhildar Great Axe, Brunnhildar Bow, a weapon enchanted with Enchant Weapon - Deathfrost, or a weapon enchanted with Frost Oil. If you can't aquire any of these and are over lvl 84 you can always get Enchant Weapon - Elemental Force - Spell - World of Warcraft.

Tips:
- You only need to learn the pets to get the achievement so you can buy them from the auction house or do them on your alts.
- As soon as you have learned the pet you can put it in a cage and trade it / put it on the auction house.

- quick tip for soloing Naxxramas.
When you get to patchwerk, find a way to get around him. run all the way to the gate. Once you stand in front of the locked gate, Alt+F4. Be sure to stand right in front of it, literally touching it. Start your wow client again. After having selected the character in the selection screen, during the loading screen, get ready to press on your auto-run. Once the loading screen have reached 100%, click auto-run. Make sure you do it while at 100%, but still not in the game completely. This will make you able to walk through the gate before your computer loads it.
