This Skinning leveling guide will show you the fastest way how to level your Skinning skill up from 1 to 300. You can skin any mobs with Skinning skill one, but the type of leather you get is determined by the mobs level and your skinning skill. You will still need high Skinning skill if you want to get higher level leathers like Rugged Leather.
Walk up to a guard in any of these major cities below and ask where the Skinning trainer is located.
Horde: Orgrimmar, Thunder Bluff, Silvermoon City, Undercity
Alliance: Stormwind, Ironforge, Darnassus, The Exodar
After you ask the guard, the trainer will be marked with a red mark on your map.
Leveling 1 - 300 for Higher Level Players
This place is recommended for characters higher than level 75. Scroll down to the next part if you are below that level.
Look for the spot on the road where 3 Dragonmaw Whelpstealers are fighting the 2 Ebon Slavehunters. (picture of the location)
1. Use an AoE ability to kill all 5 mobs.
2. Loot them and skin the Ebon Slavehunters.
3. The respawn rate is fast enough that once you finished skinning the 2nd Ebon Slavehunter, 2 new will be there already.
4. Repeat these steps until you get Skinning 300.
The reason I only recommend this place to higher level players is because the 3 Dragonmaw Whelpstealers are not Skinnable, so it would take more time to kill the non-skinnable mobs than to kill the Ebon Slavehunters. You can go this place at level 25 if you want to, but the place I recommend below is a lot better for lower level players.
If you see someone farming at this place, you can go to the place for lower levels, it works for higher level players too.
1 - 300 for Lower level players
The Black Dragon Whelps at The Charred Vale in Stonetalon Mountains have really low HP and are extremely easy to kill. They come in packs of thee, so you will level Skinning here really fast because you don't have to run around that much to chase down mobs.
These mobs scale from level 20 all the way up to level 60, so you can reach 300 by staying at this one place.
If you are looking for alternative places, then the places in all of these guides are good for leveling to 300: Medium Leather farming, Heavy Leather farmong, Thick Leather Farming, Rugged Leather farming
But keep in mind, you will be limited by your character level on where you can farm. You can't farm Rugged Leather with a level 30 character for example.
