Sorry, maybe I'm not reading clearly or I missed something, if you're a Sepcarim and you're only able to use one of the Maian energies, can you use that same energy to cast spells in any of Branches of magic. Like for example, using Xi to cast spells learned from Insorcery. Sorry if this has been answered before, the interest check went rather fast so I couldn't read everything.

From what I understand no. Insorcery requires Sakra as its main fuel, and would thus be completely out of reach for a Monk that can only utilize Xi.
