When crafting items, there is a chance you can craft two items instead of one.

For example, when smelting iron ore into iron ingots, there is a percentage chance indicated on the right side of the crafting interface that displays the chances of creating two ingots instead of one. In the case of iron ingots (and other low tier items you can craft), there aren't any other resources needed to craft it.

For higher level items that require an additional resource to craft, the chances of creating an additional item increases based on the additional resource used. An example of this is steel ingots. They require:

  • Iron ingots
  • Charcoal
  • Flux

Where the flux used to create the steel ingots impacts the chances of creating an extra steel ingot.

So, obviously the type of flux used impacts the chances of creating an additional ingot, where using more rare/expensive flux increases the percentage. The same can be said for all other items you can craft that require extra resources. But what else impacts the percentage to create an additional item? Low tier items such as iron ingots don't require an additional resource to be crafted, yet they have a chance of producing an extra item, so what influences this?

The two biggest things that contribute to bonus crafting/refining:

  • Your respective skill level
    • The higher your level, the better chances at bonus items you get.
    • Being 200 in the respective skill will grant you the most bonus and each trade skill will provide a specific bonus found when you click on the trade skill. E.g:


  • The reagent used in the craft
    • Using Tier V reagents in the craft/refining vs Tier III will increase your yield.
    • In the same vein as using higher tier reagents, you'll get more bonus materials when refining lower tier stuff. Not sure what the exact % is, but you'll notice you will get a larger amount of bonus materials when smelting iron vs orichalcum for example.
  • Oooo - didn't know about clicking on the skills in the menu to see this!

  • I can't grab screenshots of other ones, or a more useful one like smelting at the moment.
