The Demon and Arcana Ratios GDOC (created by Re) illustrates for player convenience how many demons and which arcana are assigned to each character presently in Recursion. Using the tabs on the bottom of the document you can navigate between viewing the Demon page or the Arcana page.

It is important to note that characters will not receive their Arcana at the time of their joining Recursion, but rather upon Awakening.
