In Circle of the Moon, An owl familiar can be summoned if the Saturn and Mandragora cards are used together. This familiar will fly overhead enemies and drop green globs on them. The Mandragora itself can be summoned by combining its card with Uranus and upon summoning it unleashes a series of sonic blasts.
In Aria of Sorrow, Soma, with the Alura Une soul, can summon a Alura Une behind him to heal 10 HP every second while the summon is maintained.
In Dawn of Sorrow, the Alura Une soul will Soma summon a Alura Une, which will attack enemies with its vines. With the Corpseweed soul Soma can summon a familiar of it that spits poisonous globs.

Nathan can slowly regenerate his health when idle if the Jupiter and Mandragora cards are used together. Combining Neptune with Mandragora will let Nathan gain health from plant attacks. Combining Pluto with Mandragora grants Nathan a 20% boost to experience points gained when an enemy is killed.
