Free Bambinos are found in Magatsu Mandala, once summoned by Great Kings which appear in the first World. As the Great King summons a seemingly infinite number of Free Bambino Shadows to the field (up to 3-4 at a time due to a 5 slot limit), players farm them for money and EXP. They cast Amrita to cure any status ailment that is inflicted on them and Brave Blade to attack. They may drop Royal Blossoms when defeated. Selling 6 Royal Blossoms will unlock the Kikusui Awase female armor in the shop.
In Golden it appears the same way listed above. It may drop Aurora Quartz for trade at Shiroku Pub.
