It says:

Increase Evasion Rate by 40%. Up to 2 enemy attacks may be evaded per round.

So I am wondering how it works.

First of all, Is it 40% for every possible combos attacks? For example Kisame Samehada Fusion with 10 combos standard attack, will it means there are 10 times "chances of 40% probability evading" the attack? Or,

Second, is it 40% for every possible skills attacks? (e. g. Mystery is counted as 1 attack, Standard is 1 attack, Chase is 1 attack; regardless of the combos). Or,

Third, is it 40% for every "first" attacks received (either Mystery, Standard, or Chase) and if the first attacks is successful, then the next attack (if the first attack triggers combo) will NOT be evadable?

Or HOW? Can someone please explain to me? For me 40% is high enough, like 4 of 10 attacks is evaded, or to make it into a smaller scale, Azure Fang probably will evade 1 per 3 attacks (2.5 actually, but just let's just say it's 3). But after doing some tests, it turns out that the dodge probability isn't that high. My Azure Fang often ended up killed after combo-ed (because she didn't evade the first attack that triggers the combo). I don't think the 40% rate is correct.
