Example 3:
A party of four monks attempts to stun-lock an Elite monster in Inferno difficulty. They are all using Blinding Flash with the Self-Reflection rune, which blinds an enemy for 4 seconds.
The first monk casts Blinding Flash and the monster is blinded for 4 seconds. It also now has 40% CC resistance.
The second monk also casts Blinding Flash, but times it to land the instant the first one ends. It lasts 2.4 seconds and increases the CC resistance to 64%.
Both blinds wear off 6.4 seconds later. The third monk lands his Blinding Flash immediately afterwards, which lasts 1.44 seconds. This increases the monster’s CC resistance to 78.4%.
It's now been 7.84 seconds, and the fourth monk wants in on the action. She uses her Blinding Flash. Even though the monster’s CC resistance is technically at 78.4% by now, it's capped at 65% because of the CC resistance caps in Inferno. So, the 4 second blind actually lasts for 1.4 seconds. This adds another 14% CC resistance, bringing the final to 92.4%. (The effective resistance is still at the 65% cap, but the 92.4% is tracked under the hood for the stun resistance to wear off.)
The poor monster has now been blinded for a total of 9.24 seconds, and the monks are out of Blinding Flashes. :(
The next blind will occur when the first monk’s Blinding Flash comes off cooldown. Since Blinding Flash has a 15 second cooldown, and only 9.24 seconds have passed, the party has to wait for another 5.76 seconds. During this time, the monster loses 57.6% CC resistance, leaving it at 34.8%.
The first monk uses his Blinding Flash as soon as it comes off cooldown. The 4 second blind is reduced to 2.61 seconds thanks to 34.8% CC resistance, and the monster’s CC resistance goes up another 26.1% to 60.9%.
