As I know it should work for Gracia. I press alt button and left click to the applied buff. That should take that buff off, but it doesn't work. What is wrong?
Found that those buffs I get from the buffer NPC can't be removed. But those I get in the game, can be removed.
some buffs can't be removed, im not sure how to define that, maybe it is at the client, since i didn't found anything related to that on the skilldata. also you can't remove songs/dances
Songs/ dances is retail. About the other buffs, its defined in server-side, not client. Some L2off guru will have to clear this.
