Cleansed

''Enchantment. The waters of the Fountain of Truth have washed away your sins. You are now worthy to transport the Eye of Janthir.''

As the description says, being cleansed is a requirement to be able to transport the Eye of Janthir in the mission Divinity Coast. Only if all party members are cleansed will the Eye follow the group.

Being cleansed has no other side effects.
