# Calculating Enhancement Bonus

Many are under the false impression that you ADD the percent of the dragon skill to the percent shown under dragon skill enhancements.  Wrong.  It would be nice though.  KOA is not that nice to us.

Enhancement percentages only apply to the bonus percent that the dragon skill provides.  Sounds confusing, I know.  Especially since KOA adds other percentages together in the game.  Not in this case.

## How-to-Math

First, you need to know how to find a percent of a percent.  Sounds easy right, but if you multiply 60% by 42% you get 2,520%.  So that isn’t correct.

In order to calculate a percentage of a percentage, you must first convert both percentages to fractions of 100, or to decimals, and multiply them.

1. Convert Percentages to Decimals

42 / 100 = 0.42
60 / 100 = 0.60

2. Multiply

0.42 * 0.60 = 0.252

3. Convert Decimal to Percent

0.252 * 100 = 25.2%

So, this would mean that you will gain a boost of 25.2% on Infantry Health by enhancing your Level 27 Infantry Backbone I to 5 stars. But don’t forget that you still get the original 60% boost so you want to add the two together to get the total % your stats will be increased by.  For this example it is 85.2%.
