My Thought of the Day: Max Tenacity on Irelia

So for max tenacity (not including olafs ult), but with just items, and masteries I found to be 75% on irelia.

Here is my math =D

We first add the mastery tenacity which gives us 15% tenacity. So now we feel the effect of 85% of the cc. Then we add in merc tread tenacity (35%).

0.85*0.35 = 0.2975.

0.85 - 0.2975 = 0.5525.

So now we feel the 55.25% of the effect of cc.

Now we add in the elixir of Iron which grants 25% tenacity.

0.5525 * 0.25 = 0.138125

0.5525 - 0.138125 = 0.414375

So now we feel 41.4375% of the tenacity.

Now we finally factor in Irelia's passive which gives us 40% cc reduction with 3 or more people around.

0.414375 * 0.4 = 0.16575

0.414375 - 0.16575 = 0.248625

So now we only feel 24.8625% effect of the cc.
