JMS v302 - Kanna

But when you use 孔雀開き, 紫扇仰波 = 240ms, Hits: 250 * 2 + 250 * 0.6 * 3 = 950
With a Viper, 210ms, Hits: 285 * 2 + 285 * 0.6 * 3 = 1085

Boss damage+% is certainly less effective, but it still works.
紫扇仰波 Damage = (100) * (210% + Boss Damage% + Total Damage%)

So if you can hit 999999 with 紫扇仰波 or have have less than 20% Boss Damage/Total Damage (AFTER SKILLS), it's better than 破邪連撃符.

Oh, you're right. Thank you for teaching me.
I'm so conversed of Boss damage's structure.

Would you teach me about Hero's Combo Attack's less critical damage ?
In JMS, no one can explain about it.

By the way, according to newly I heard, Kanna has some bugs.
First, Shoujou Kasyu's damage doesn't occurred. It could be a reason of her using Haja Rengekihu.
Next, Kekkai Kikyou's effect "Boss damage +%" doesn't occurred. But it is only a rumor, I didn't inspect.
