I Figured I'd give it a shot.
Went to Korrokola with an Iron ore. Ran to the "Worm Pit" as it is called, and saw the ??? right away.
Traded my ore.
Fought the Worm (while two other worms had their fun with me) and got 3 coppers, One tin, an Earth crystal... and the Tathlum
First try!
Sweet.
Now I can finally get <dispel> and pty again!
