Stats & level growth

Preview Siren’s stored stats at a selected level. How the game assigns a summoned Esper’s level is not yet verified; this does not set its level in your build.

Preview level

HP: 500
MP: 100
Strength: 40
Stamina: 40
Magic: 90
Spirit: 60
Speed: 30

Base stats plus stored growth through level 1, before any battle effects. These stats are not added to the summoner.

Summoning & availability

Fina and Archwitch Fina can summon Espers after the required story progression. A normal summon costs 50 MP and stays for three turns. Only one Esper can be summoned at a time.

Summoning Ifrit brings an ally into battle. Hellfire is one of Ifrit’s combat actions; summoning him does not mean he casts Hellfire three times. Each Esper has its own combat kit and AI.

Being listed here does not confirm that you have unlocked Siren or that it is obtainable in the demo. The builder offers reference planning only.
