Eternal Rivalry - Quest Guide

How to Complete Eternal Rivalry

This quest becomes available after you have done the Odd Places quest and unlocked a location in Sant D'alsa Bluff via that quest.

You are not actually supposed to do anything in this quest except survive. There will be an earthquake every two rounds, damaging all units. You are not allowed to restore HP, but you can use the Regen clan privilege if you have it.
