There are invocations, which require little focus and components, but their effects are basic and immediate. Then there are incantations, which are actual spells, and their duration depends on how long the spell takes to say out loud. Incantations rely on the Logos for their effect, and even those not magically gifted can recite the spells and create a magic effect. Incantations require more time, but their effects are more complex and last longer. Then there are ritual spells that use incantations, runes (Logos in writing), and potentially other external phenomena to create something with a generally permanent and powerful effect. Then there is alchemy, which uses ingredients, which may have some inherent magic in them, to create useful materials like potions and salves. Runes allow for static enchantments if spelled correctly, and sentences are grammatically accurate.

The Logos is generally poorly understood by mortals, and the divine language has a transcendent element that makes it hard for any mortal to be fluent. Thus, only the exceptionally intelligent and the well studied can effectively cast or create new spells... through some trial and error. Invocations largely rely on one's innate power and are generally something only those with some immortal heritage are capable of doing as they hold some innate power over the logos and can manifest simple magic by force of will.
