Just remember, the foucs+hex don't work against monsters assigned, which aren't slayer monsters. (Eg, they don't need a certain slayer level to kill.) Thus, it will boost vs abby demons, but not black dragons. Lame. Where did you get that info? i think what stone means is that you won't get the bonuses from the hex or sight unless your using them on a slayer task. non-slayer tasks will not give u the bonus of the items. and you will get the bonuses on any slayer task. it doesn't matter if they require a slayer lvl or not. No, it will not work on non-slayer monsters regardless if they're your task or not. You can only get the bonus if you're on task killing a monster that requires a slayer level to kil.
