>>712959913The entire game is built with "multiclassing" built in from the top down. You get three major path options, which are largely self sustaining kits that don't always rely on any others to function within itself. Novice (lvl1), Expert (lvl3) and Master (lvl7).
As you pick paths, their abilities will be piece mealed to you at various levels while the character progresses. Novice starts with 1 of 4 options (Warrior, Mage, Priest, Rogue), each with their own in-path character options you can pick, be it abilities or spells. Characters who delve in magic must learn a school of magic (at the cost of a spell slot) before they learn spells in it, so specializing in one school will always net the most overall number of spells, while learning multiple schools will reduce your overall number of total spells for the flexibility. Spells have an individual number of charges per rest, so they aren't ever fighting with each other over castings per day like in D&D; you get X number of castings based on your Power score in conjunction to the spell rank, and casting that spell does not limit any of the castings for others you may have learned.
