Magic Shrines of Ambrosia

The Shrines of Truth,also at times called the Shrines of Knowledge or Shrines of Strength, are ancient holy sites located on the lost continent of Ambrosia during Ultima III.

Description
There were four shrines to be found in the strange realm of Ambrosia, dedicated to the attributes of Strength, Dexterity, Intelligence and Wisdom. Developed by the long dead ancient race of the island-kingdom, these places were imbued with the power to change the physical being of those who prayed at them with appropriate tribute in hand. For an offering of one-hundred gold coins, an individual could raise their skills in the area the shrine represented by one measure.

During the Stranger's quest against the hellspawn, Exodus, the hero and their companions could learn of these sacred locations from the people of Moon or from the prophet Radrion. Here, in addition to finding a means to hone their abilities in preparation for their battle against the daemon-machine, the four heros would also discover the Four Cards necessary to enact Exodus' destruction.

Lore
''Shrines there are again but four to which you go and pray.  their uses are innumerable and clues throughout I say.  - Radrion's prophecy (Ultima III)''
