We apologize for the confusion this issue might have brought.

Please note that there is an issue on the script of the skill “Earth Prison” being displayed incorrectly.  

The effect of the skill script is being displayed as if it has “stun” effect.

However the original effect of the skill is “immobilizing.”

Immobilized monster can still attack players while it can not move.

We have verified that the skill works properly

And this issue will be fixed soon.

Again we sincerely apologize for the confusion caused by this issue.

Thank you
