Procne

Procne is a Summon sequence of the Jupiter element. When three Djinn of the Jupiter Element are on standby, the Procne Summon sequence can be activated. It resembles a divine, beakless bird bring up and incapacitate enemies in the sky with a giant tornado, then attack the foes with Jupiter Psynergy before letting them drop down to the ground below.

Procne has a base Jupiter power of 120 and also does additional damage equivalent to 9% of the enemy’s maximum HP. Procne is the first truly useful Jupiter summon sequence. It is twice as powerful as Atalanta but uses only 1.5 times the amount of Djinn on standby. It can be very effective in the boss fight against the Killer Ape in Mogall Forest.

Cultural Allusions
In Greek mythology, Procne was the daughter of Pandion and Zeuxippe. She was turned into a bird by the Olympian gods (the species differs, but the most common is a nightingale or a swallow).
