Master Digler:
In order to renew the power of the damaged amulet, we need the Divine Stone of Wisdom and its strong spiritual power.
That stone is possessed by two great magicians: the Soul Guide Asefa of the Ketra Orcs and the Soul Guide Udan Mardui of the Varka Silenos.
They will award the stone to the most intelligent ones among their kind. If you can gain eithers' trust and prove your worthiness, they will give you the stone.
There is no other way than to obtain the Divine Stone of Wisdom other than from them. What will you do?
Get the stone from the Ketra Orcs
Get the stone from the Varka Silenos
