Monster's Skill

Good evening, i have a little problem with the monster's skills, i'm not able to dispel some debuffs that are regulary dispelable, i tried to check their skills, and to search those skills into the skill file, but nothing, is there a file or something where i can edit the skills?

Hello, you can find the file in Monster Folder Name "NPCskill.sdata" . I recommend you use the search funktion there is already some questions&answer.
