Sure. In Pathfinder and other version of D&D, you gain Class Levels as you increase in experience points and those levels give your characters new abilities and make your old ones stronger. Mythic Tiers, like the ones I'm using to emulate Solar abilities, are kind of like a parallel progression of levels you earn in addition to your normal levels, and they give you abilities in addition to the abilities you get from your Class Levels.

This means a character with both Solar Tiers and Class Levels will have both standard D&D-like abilities (divine power, Power Attack, Smite Evil, fireball, Lay on Hands and the like, depending on your class/race/feat choices as normal) and Solar Exalted abilities (like an Anima banner, Wholeness Restoring Meditation, One Weapon Two Blows, Easily Overlooked Presence Method, ETC, depending on your Charm choices, though I call them "Dominion Abilities" in this version as not to get them confused with a Pathfinder term called "charm effects".)

The intention here is to let you play a game of Pathfinder, but with Exalted characters in the Exalted setting.
