Keystone

Keystones are important artifacts released with the Funkey Trunk expansion.

Description
Upon entering Angus Manor, Angus tells the player about the Keystones. He first discovered them after meeting a unique Familiar, who gave him the Stone. He had never encountered the same Familiar since, and he has not found any more Keystones.

A Keystone can be obtained by reuniting a Familiar with their Funkey. This is done by using a Familiar while its respective Funkey is on the dock. Once this is done, the Familiar will reward you with a Keystone.

The Keystones can be used at the elevator in Angus Manor to unlock a new game developed by Angus.

Trivia

 * Even though there are 27 Keystone slots in Angus's elevator, only 23 can be obtained due to the amount of Familiars released.
