I don't know. It's working pretty well here. It must be something with your current setup. Anyway, this is for PRE-RE and not Renewal, so it serves its purpose. When the skill effect was removed, they rebalanced the skill to be faster. This code is meant to bring back the Sonic Blow animation to PRE-RE, not RE, which won't fit due to the new way the skill works. So, in other words, it isn't working because you're not using it for the purpose it was coded.
