Abjuration - This is the domain of protection. Depending on someone’s attunement, this will manifest their magic in different ways. Observed uses are mana-based Energy Shielding, which is what Gisele does. She projects a shield onto a location of her choice that is capable of stopping physical and magical attacks. I suspect its strength will increase over time. Another observed manifestation of Abjuration is Healing. I am unsure of the extent of or types of healing spells one is capable of using, but Maud is capable of using her Heal spell to repair nearly any physical wound. Her only limitation seems to be how much mana she can channel at once. The last function of Abjuration is merely theoretical at this point, but I suspect that Dispelling is the last function of the Domain. More observations of magic users are needed.

Alteration - This is the domain of change. This domain will manifest in the ability to either manipulate materials physically, such as being able to Shape various metals. Also, I strongly believe Alteration allows for the Manipulation or Shaping of spells and mana.

Artifice - This is the domain of empowering and manipulating the properties of objects. Classical fantasy would probably call this enchantment, but my observations have shown that it includes so much more. Artifice allows one to Identify objects and their function. Also, I suspect that Artifice is required to Empower objects and runes. Artifice may also be required to Imbue intent into gems runes. This domain is the cornerstone of all of my future money-making potential.

Conjuration - Conjuration is the domain of Summoning and Materialization. I believe this domain will be able to Summon magic (possibly even physical) creatures or companions. Further, I believe this domain is capable of Materializing objects or … materials. Further tests are required.

Divination - The domain of information, detection, and foretelling. Depending on the attunement, I believe this domain will allow users to use magic to Track, Scry, or even delve into Potentialities.

Evocation - The domain of energy creation and manipulation. Evocation is what everyone thinks of when they hear the word Mage. Whether it’s casting a Mana Bolt or even the timeless Fireball, evocation allows you to draw into your attunement and manifest the elements into the real world.

Illusion - The domain of smoke and mirrors. This type of magic allows a user to create spells based on false images or scenes. Further, illusionists can also use the domain to Obfuscate themselves from others to remove themselves from view or even thought. Stealth is likely a mainstay of this domain for the rogue in your life. I believe any damaging effects from this would be more mental in nature. 

Mind - The domain of mental effects. Depending on the attunement, this can take various forms. From offensively attacking someone’s mind through something like a Mind Blast, to protecting another’s. Perhaps even Mind Heal or Soothe, or Manipulating it. I believe this can also manifest in Coordination or Telepathic Communication which would be highly sought after for squad-based units.
