VS life stone Bug

[KOI]

Sorry I don't know English. The following is the Google translation content
The VS life stone soul blow
When using
Skull Basher
, enjoys 25% stun probability in melee combat
When you upgrade to: Abyssal Blade
It was supposed to have a 25% stun probability in melee combat, but the actual probability is 10%. I guess it's a bug, and the soul blow effect didn't take effect.

以下是中文原文：
vs 在使用命石效果 “灵魂打击” 并且装备 “碎颅锤” 时
会正常应用近战25%眩晕效果
但是“碎颅锤”升级为“深渊之刃”后
理论概率为25%，但是实际测试后概率为10%，命石的“灵魂打击” 远距离攻击享有近战效果 并未生效
应该是bug吧

我在斧王岛试了一下，在vs打出眩晕时立刻按s等待数秒后再次攻击所触发眩晕的次数基本都在三到五次；而触发眩晕后不按s继续攻击至下一次眩晕时所触发的次数则多得多，攻速越高次数越多。并且从未观察到连续触发眩晕的情况。推测是深渊之刃和碎颅锤一样存在内置cd但并未像碎颅锤一样在物品介绍上写明。
