Hi I'm not sure if this is still the case or not. I don't really want to test it because its a waste of my dire charm 
Anyway, the charm only works on mobs that are level 50 or less. But when I used to play (years ago), if I would cast it on a mob that was higher than level 50, it would be wasted. It wouldn't charm the mob, and yet it would use up the charm, and I then had to wait an hour and a half, or however long, for it to be re-usable again.
Unfortunately, its impossible to really tell what level a mob is, by just conning it and looking at the colour. At level 65, you really want to use the dire charm on a level 50 mob to get the most of out it (its verging on useless as it is, so you really need a level 50 mob). And a level 50 mob is just dark blue, but so is a level 51, and so is a level 49 etc.. So I'm assuming you wouldn't want to give us a way to identify the exact level of a mob, but I am hoping you might consider altering the dire charm AA slightly, so that if you use it on a mob thats higher than 50, it doesn't get used up.
Currently, I have a character that I leveled up to 50 especially just to con things... But I would really like to continue leveling that character up to 65, and I really don't want to have to make a new character and level it to 50, just to con things. So this would be something I would really appreciate anyway, and maybe other chanters would like it too.
p.s. If you wondered whether this is a worthy tweak, please just ask me, because I think I could justify it.
