Eldritch Esoterica

Eldritch Esoterica (陰陽の大全集) is one of Zexion's weapons in Kingdom Hearts 358/2 Days. It can be upgraded to Eldritch Esoterica+.

It allows Zexion to perform extremely well in midair, and also highly increases his Strength. Eldritch Esoterica's combo finisher involves Zexion transforming the Esoterica's shape into that of a bird and making it fly, making the enemy, whether airborne or in the ground, take massive damage.
