Make 1000 Frog Mutants devour each other, and the last one remaining becomes a Frog God. Its skin is covered with poison. It eats anything that moves.
This creature is usually paired with 2 Mutant Frogs, this creature has a higher HP then the Mutant Frogs so it may take more than one attack to kill them. At Dalian they appear in 3's which is a good advantage to use to get the Heaven's Fiend.
