This calculator will let you estimate how many attempts are needed to skill up and how much your skilling up will cost you. It assumes that you make one single item until it is trivial or until you reach the maximum skill of 300.
Enter in the values listed below. If an item is marked optional, you can leave it blank. Most values should be self-explanatory. For more information, click the Show help button.
Item Trivial: Put in the trivial of the item you are attempting to combine.
Starting Skill: Put in the unmodified skill of the tradeskill you are using.
Primary Stat: The prime stat is the higher of INT or WIS. OR if you are doing smithing it is the highest of your INT/WIS/STR. If you are doing fletching or poison making it is the highest of your INT/WIS/DEX.
Mastery level: Choose your mastery level in that tradeskill, or zero if you don't have any mastery.
Cost of components per attempt: This is the total (in platinum pieces) that all the components cost you. Gold, silver, and copper pieces would be decimal values. For example, 10pp 5sp 3cp would be 10.053.
Sellback on success: This is how much you can sell a successful result for. It could be to an NPC vendor or to another player. The calculator assumes you sell all of your successful results for this price.
Recovery on failure: This is the value of the items you receive back on a fail. For most recipes, this will be zero -- you lose everything on a fail. However, some recipes will always return one or more of the components when you fail an attempt.
Max chance of success: A few items have a maximum chance to succeed, regardless of your skill, modifier, or abilities. If you know this value, enter it here.
Bonus chance to skill up: A few items have a bonus chance to skill up. If you know this value, enter it here.
Skill modifier (geerlok, etc.): This is the skill modifier you have equipped when doing these combines. It could be a geerlok, a trophy, or another skill-modifying item.
Desired Skill: Normally, the calculator assumes you do this one combine until the item is trivial. If you have a target skill below the item's trivial where you want to stop, enter this here.
