Even though the guide was developed with a hunter, the guide can be followed by any class. Except you have to do your class's quests which aren't a whole lot. I do have full intention to make my guide friendly with all classes in the future by listing all of their steps as well. There will be a toggle that allows you to show which class's steps you want to see in the guide. But this is coming later.
To gain gold in World of Warcraft, you will primarily be grinding professions which are fantastic for receiving rewards. Mining is an example of a great profession at an early-game level. While Herbalism is actually the best gathering profession, the issue is it uses consumables which can make the profession rather costly, with the investment required.
Cold Eye Basilisks (marked RED on the map) - Western shoreline of the middle Stranglethorn Vale is infested with deadly Basilisks. These monsters are a good source of Heavy Leather and Thick Leather (we recommend Skinning for this spot), they also drop a lot of Vendor Trash Items (Curved Basilisk Claw, Intact Basilisk Spine, Large Basilisk Tail, and Squishy Basilisk Eye), Large Fangs (used in Leatherworking, Blacksmithing, and Alchemy Recipes), Wicked Claws (used in Leatherworking and Blacksmithing Recipes), 12 Slot Bags, and most importantly, Cold Eye Basilisks have a small chance to drop the Cold Basilisk Eye (a level 35 BoE Trinket, that can be very valuable, because useful Trinkets are rare in Classic). Recommended Level - 38+.
This Shadow Talent Build is the fastest for Leveling Up a Priest Class from 1-60 in WoW Classic patch 1.12. Spamming Shadow Damage DOTs while kite mobs will be the name of the game with this build, having the ability to sustain your health is just a bonus. You will just need to make sure you are stacking enough spirit so you don’t run out of mana often as that will slow down the levelling process drastically.
Kurzen's Compound (marked BLUE on the map) - Colonel Kurzen was once a very talented Stormwind Officer. He was sent with an expedition to the Jungles of Stranglethorn, where he fell victim to Mai'Zoth, a powerful Ogre Mage and his foul magic. Majority of Colonel's troops are still loyal to him and provide Players with some valuable Loot. In this spot, you will encounter Kurzen Jungle Fighters, Kurzen Medicine Men, Kurzen Wranglers, and Kurzen Commandos. These Humanoids drop a lot of Silk Cloth (that can be generally turned into Bandages and Vendored), valuable Wool Cloth (the main source of Gold from this spot, check the AH prices), Fadeleaf (Medicine Men), Liferoot (Medicine Men), 12 Slot Bags (Commandos), Vendor Trash Items, and some Pocket Money. This spot is especially good for Rogues, as the ability to Pickpocket mobs will increase profits by a noticeable margin. Recommended Level - 34+ (36+ to be extra safe, as Humanoid mobs can be problematic because they tend to run away on low health and pull additional enemies).
