Head Priest of the Earth Daichir:
Defeat the monsters that are threatening the safety of this world. I'll tell you which ones to defeat.
First, you must defeat Istina, Octavis, and Tauti in an Epic Battle. You must also defeat Beleth and Earth Wyrm Trasken, and bring a Dark Soul Stone.
However, defeating Earth Wyrm Trasken is difficult. That's why I have another method. Would like to hear it?
"What is it?"
