Summon

From IvaPedia

Syntax: summon <aeon/list>
Syntax: command <skill>

This skill allows a summoner use call for the aid of a magical beast known as an Aeon. While this is very costly to the summoner herself, costing nearly 1/4th of her entire mana pool, while in her command, an Aeon provides both protection and safety to the Summoner.

Some commands are learned automatically as a Summoner and her Aeon progress in their skills, though others require special training to learn - Similar are the Aeons themselves - All summoners have basic knowledge of Aeons, but only those who travel the world learning their ways will master them all.

While a Summoner controls an Aeon, in battle or out, she must expend her own mana to keep it attuned to her - The cost increases with the summoner's training - although out of combat the time between the Aeon's draw is spaced, in combat the Aeon requires additional mana each round it fights. Similarly, various commands draw the Summoner's mana through the Aeon for execution.

The aeon skills cost a set percentage of a summoner's mana as opposed to a fixed amount.
