Optional reagents are new types of reagents that can change the item level and the secondary stats of the items you craft. You can probably guess from its name, but it isn't required to fill the Optional Reagent slot when you create something, you can craft an item with no optional reagents or you can fill as many Optional Reagents slots as you prefer.

World of Warcraft Classic is a faithful recreation of the original World of Warcraft—it runs a bit smoother on today’s computers, but the game still looks and feels like you’re playing World of Warcraft from 2006. Below you can find profession leveling guides for every profession in Classic World of Warcraft.
Rise of Azshara Patch 8.2 goes live on June 25. / 26. (US/EU). The new patch offers a lot of new recipes and items to craft or gather.
- All Battle for Azeroth professions (except Archaeology) now have a maximum skill of 175 instead of 150. Every old recipe will be gray after 150, so you can only use the new ones to level your profession up to 175.
- Players can now gain the first 25 skill points in each profession by disenchanting, milling, or prospecting items from the respective expansion. These are not guaranteed skill points, but still, it will be a bit cheaper to level up these professions.
In the upcoming 8.1.5 update on March 12, players can take part in unique quest lines for the Alchemy, Blacksmithing, Enchanting, Engineering, Inscription, Jewelcrafting, Leatherworking, and Tailoring professions to earn a new Tool of the Trade that complements their craft.
I recommend trying Zygor's Leveling Guide if you are still leveling your character or you just started a new alt. The guide is in a small window on your main screen in-game, you’ll never have to switch back to a website or even the in-game main map to see where you have to go or what’s next. I use Zygor's guide for leveling, and I highly recommend it.
