Hello everyone, im developing a l2 aCis server and i need little help with the monster skill that are found after clicking on the monster target. I want to delete these skills visually from the monsters target. I deleted them from npc xml but they are not deleted from the target. Any ideas? https://ibb.co/xgwCZWK
