Hides
Every time you skin a fallen beast you have a chance of creating hides instead of a regular skin. There are several basic hide types
such as light, medium, heavy, thick, and rugged, as well as creature-specific hides such as raptor and shadowcat hides. These
hides are sought after in leatherworking. In Outland, you can create fel scales, cobra scales, and other creature-specific
hides from beasts only found there. Like all hides, you will find a market for them on the auction house.
Alterac Valley
You can skin certain animals in the Alterac Valley battleground to help your side win the battle.
300+ Skinning (Pre Burning Crusade)
You can increase your skinning over 300 with a skinning enchant and a few items exist that add to your skinning skill. It's rumored
that there are some quests for 300 and up skinners. There are some high level monsters that can be skinned with 300+ skinning to
gain certain rare objects like Pristine Hide of the Beast or Onyxia Scales. These can be used in quests or recipes to create more
powerful items. High level Raids sometimes need a skinner with max skinning. The items skinned can be very valuable to the guild.
Master Skinning
To get master skinning (375 maximum skill) you need to travel to Hellfire Peninsula or visit Seymour in Shattrath City. Alliance players can
visit Jelena Nightsky in the inn at Honor Hold. Horde players can find Moorutu in Thrallmar right outside the inn.
To raise your skill from 300 to 375 is a long process. On average, you will gain a skill point in one in every 5+ successful skin attempts.
Some suggested beasts to hunt are hellboars, ravagers, talbuks, clefthoofs, and nether drakes.
Skinning higher level creatures will give more leather; you will not get a single leather scrap.
