Summon

Summon is a rare ability that only a select few, the triple-liners, can use. It is the ability to call upon a god's strength from within a magic wand. The summons are named after ancient mythological figures.

Description
A wand transforms into its true form after a successful Summon. According to Cell War, a wand unleashed via a Summon doesn't just have its own power enhanced. The level of magic power the caster can unleash becomes "incomparable". With a Summon, entry-level spells can be as powerful as Secondth spells.

A dark lightning-like effect is shown whenever a Summon is activated.

Trivia

 * Decius is currently the only named Summon without a known epithet, due to Famin having it activated without chanting its name. Decius's name was only revealed in katakana through its Thirds.
 * Doom is the first triple-liner to summon a god that is not from greek mythology.
 * While not possessing a Summon due to a lack of magic, Mash named one of his strongest techniques after one from greek mythology, namely Gaia.
 * Both Adam Jobs and Innocent Zero have a Summon that is linked to Darkness. It's unknown if those Summons are actually the same, due to their different appearances.
