Have you found the Tzhear area??
- Kill the Tz______ people and they will most of the time drop some.
- Do the Cave minigame (NOTE: YOU WILL NOT LOSE STUFF IF YOU DIE) and the farther you get the more Tokkul you will recieve.
- Do the Other Minigame down the path (NOTE: YOU WILL NOT LOSE STUFF IF YOU DIE) and if you survive- and reach #1 you I believe will Recieve Tokkul.
And for any more Runescape information you can use http://runehq.com/ and work your way around their database..
