Level 18

This is the second stage where you fight an epic monster; Rhynex, who is backed up by two Utochomps.

Strategy
Monsters: Bonbon, Freetle, Thundenix (or Pandaken)

Rhynex, unlike the Scorchpeg in the previous level, deals less damage, but has Poison, which takes away 10% of a monster's health each turn and lowers his damage output, but it shouldn't be a big deal if you have a healer like Tarzape. Bonbon can kill the Rhynex with ease and then you can let Pandaken, Freetle or Thundenix kill the Utochomps.
