Persona 3 Reload introduces a variety of mythological creatures from different cultures around the world. One such creature is Decarabia, the 69th demonic spirit listed in the Ars Goetia. This powerful demonic presence can be fused and summoned by the player.
Decarabia belongs to the Fool Arcana and is tied to the SEES Social Link. As the Fool Social Link levels up through story events, fusing Decarabia later in the game will grant more bonus experience for the Social Link. However, it is important to note that the player must meet the prerequisite level 54 requirement to attempt to fuse Decarabia.
To acquire Decarabia, the player needs to defeat the Tartarus boss Isolated Castle on floor 143 and obtain the Pentagram Stone. Only after obtaining this item will Decarabia appear in the fusion list.
Decarabia is a robust Persona in battle, with its only weakness being Slash damage. It also learns two powerful Almighty spells and Tetrakarn to offset its Slash weakness. Unlike Special Fusions, Decarabia can be fused through a Dyad Fusion.
There are multiple fusion combinations to obtain Decarabia, but here are the five easiest combinations:
Choose any of these fusion combinations based on the Personas you have unlocked, and you will have Decarabia ready for battle.
Remember, Decarabia is a powerful ally that can aid you in your journey through Persona 3 Reload.
