Ace Ultima

Whenever characters go up from the Mortal to the Exalted Stratum, increasing in divinity, they also unlock their Ace Ultima. The Ace Ultima is a special ability unique to the character, and represents the peak of their prowess, and their dominion over a certain domain or force in the universe.
When the Ace Ultima is unlocked, select one out of the 22 Arcana Cards seen below, and add them to your Gambit. Each Arcana possess a value of 10, and is associated with two Ways of Magic:
The Ace Ultima follows the same rules as crafting a spell. However, instead of using magical effects you have learned, you use, and gain full access to, all magical effects of the same or lower Stratum than the one you possess, from the two Ways of Magic associated with the chosen Arcana Card. Then, using the magical effects from the two Ways of Magic, craft a spell with a maximum resource cost of 5 or less, this spell becomes your character’s Ace Ultima.
Access to these magical effects only extends to crafting your Ace Ultima, and cannot be used nowhere else in the system. If you already know any magical effects, you cannot use them to craft your Ace Ultima, unless they belong to one of the two Ways of Magic associated with the chosen Arcana Card.
Whenever you use your Ace Ultima you do not expend any resources, and must instead remove the Arcana Card from your Gambit, as you would when expending cards with resources, like Might, Numen and Fate.
Every Long Rest you can change the spell that is your Ace Ultima, but must otherwise follow the same rules, and you cannot change the chosen Arcana.
Ascending Above Exalted
Once you ascend to Exalted or above, and already possess a Ace Ultima, you can select another Arcana Card from the list to add to your Gambit, and craft a different Ace Ultima based on the newly added Arcana. However, Ace Ultima from different Arcanas are not interchangeable, and you must expend the specific Arcana Card to use its Arcana’s Ace Ultima. If you instead choose an Arcana you already possess, you simply gain another use of your Ace Ultima.
Additionally, the maximum resource cost of all your Ace Ultima also increases, and is dependent on your Stratum. The maximum cost of your Ace Ultima for each Stratum can be seen below:
Stratum 	Mortal	Exalted	Demi-God	Empyrian
Maximum Ace Ultima Resource Cost	5 	10 	15 	20
