So i used ap because it is easier since you dont need to worry about base ap since there are none. I had 500 ap in items no runes/masteries. 30% from death cap 6% from dragon 702 ap in total 500*1.3*1.06=689 therefor multiplying %bonuses does not work.

This is how ap work with 2 different % bonuses

1*1.3 = 1.3

1.3*1.06 = 1.378

1.378-1.3 = 0.078

now, that difference has not been multiplied by 1.3 yet right? so

0.078*1.3 = 0.1014

0.1014-0.078 = 0.0234

now, that difference has not been multiplied by 1.06 yet right? etc.

After you do that a couple times you add up all the differences and 1.3 and equals to 1.40358... and that times 500 = 701.62932... if you do if the exact opposite, starting with 1.06 you will get the same answer. https://docs.google.com/spreadsheets/d/1-DeE5mXkpOIk_a25y5z7AZtXyQcpMe8qThM0uGG6i4M/edit#gid=1899291800 is a spreadsheet i made. my only problem is trying to find a formula.
