How long does it take to reach lvl 55 slayer? How often do turoths drop mystic robes?

Turoth drop around 1 every 500 kills, same rate as other mystic from other monsters.

 

To get to 55 really depends on your tasks, if you play alot you can get 50k a day easily.

 

 

 

Good luck

Like with all other skills, it takes time to level up.

 

 

 

I'd suggest going to the best slayer master you can. And fight the metal dragons then you're aggismennted, they have good drop and give a lot of Slayer EXP. Some people say you should ignore them, but I wouldn't. It's totally up to you, but I must warn you, they are far stronger than the color dragons.
