These books cost 1.000 Gold each and are sold from your BfA gathering profession trainer. As soon as you re-learned your farming profession, use this book and you will get back all of your lost Battle for Azeroth gathering ranks. Your gathering skill remains reset at 1, but you don’t have to care about that since you have your ranks back – thats literally all that matters.
At 96 the standard wisdom is to immediately drop what you're doing and proceed to Spires of Arak and do the quests to unlock the Inn, granting a further 20% experience bonus while in that zone. You'll want to do that eventually anyway, but I'm not sure it outweighs the quest experience from Gorgrond. However, if you decided to go to Spires immediately at 96, restrict yourself only to bonus objectives and again leave Treasures until you're 100+. Make certain that when you being the quests to unlock the inn, you speak with the quest NPC to also learn Archaeology, since it's required to collect several of the treasures in Spires.
When buying raw materials from the AH, keep an eye out for bargains. Choose only the cheapest items available to keep costs down. Try scanning the whole section of item listings in the AH to check prices; often the prices for stacks of items in the AH are much cheaper than individual pieces (for example, a single Thorium Bar may be priced at 3 , but a stack of 10 may actually be priced at only 2 per Thorium Bar) — you may spend more to acquire your materials, but you also save more and ensure larger profit in the long run. You can find a lot of terrific bargains this way.
Enchants. I honestly wasn't 100% certain which enchants were best, since scaling has screwed up a lot of things. IMO, just pick the enchant for each armor slot that has the highest bonus without level restrictions. The exception is that you'll definitely want Mark of the Hidden Satyr for your neck piece, and probably Elemental Force for your weapon. Both of these proc consistently and strongly across all levels.
For this farm we're taking it all the way back to eastern kingdoms. We're going to be killing the purespring elementals in the purespring cavern for the item essence of water. Essence of water is a semi-rare drop that goes for a shocking 252g per piece. The caveat is that it doesn't drop all too often, but is still worth the trouble. I wasn't getting TOO many of these, but I was still making bank with them. The essences are used to create the old-world illusions, so they do have some inherent value. Simply patrol the area and kill as many elementals as your heart desires. It's a really cool and fun farm that can be done on autopilot. Usually there is noone patrolling the spot.
This new farm takes advantage of the level scaling changes implemented by blizzard. Event NPC's like the NPC's found in the twilight outpost, scale up or down depending on your level. HOWEVER, your level also determines which loot tables each mob will have. By using a level 58 character, you can successfully loot items in the 57 – 59 item range, a range which has some of the most expensive and well sought after transmog items in the game. In less than 30 minutes farming this spot I was able to snatch up some glorious legplates[/URL] (on video) – worth a stunning 150,000g. Watch the video for absolute details I suppose, but the gist of it is you need to create a level 58 DK, go to the twilight camps, and start the killin'. Unlike before, an implementation of a daily event has changed the loot tables! This spot is the new hot thing on the block.
Flipping is the least time consuming way to make gold in WoW. It simply involves trading on the auction house. You buy low and sell high. There are a lot of different markets you can try your hand in flipping both Legion and old world. Flipping works best when there are natural variations in either demand or supply for an item which will cause the price to vary over time.
Materials ('mats') - items that get used in professions. This is driven more by use than by source; for example, copper is very easy to mine, but it is widely in demand, and you can often find bargains in copper, bargains you can profit from. Contrarily, some very scarce mats may have low demand, may only be used in one mediocre recipe, and may not sell.
Now that we have a lot to post we reached a point where we have to plan what items we post on an 12-24-48 hour cycle. The auction house fees for Warlords of Draenor items are extremely high. And the values of the items are really screwed up. A lot of the weapons or armor has an item value of 5-10.000 Gold. But they look plain bad and the chances of selling them is pretty low.
