Sphere Recommendations

NOTE: The sphere letters below are hyperlinked to our Sphere Hub which lists all available spheres sorted by effect!
  • A Sphere - Melee Attacker that wants ATK or BRV DMG Spheres

  • C Sphere - Applying a healing sphere, specifically Nine or Ceodore will make Caius unkillable as long as Doom is applied and the enemy tries to kill him on their turn. Here's how it works:

    • Enemy attacks Caius with lethal damage

    • Heart of Chaos sets Caius HP to 1

    • Caius Doom debuff attacks and breaks the enemy (doesn't work on enemies with mBRV floor)

    • Sphere triggers and heals Caius

    • Heart of Chaos sees Caius HP is not 1, does not full heal, does not dispel itself, making Caius immortal

  • D Sphere - Boost party's ATK

How-To-Play Notes

  • All of Caius's buffs & debuffs are up at Quest Start, so choose whichever skill makes the most sense based on the situation and considerations below!

  • Giga-Graviton isn’t tied to a buff, so you can use it as needed to instant break or push enemies back a turn, just make sure any of his Chaos debuffs are applied to get the instant break. Free use on AA or S2 to reapply Doom debuff. It also does a truckload of damage which is great in high Force HP DMG Bonus!

  • Pulsar Burst is used to upkeep his Guardian buff. Good for single target fights.

  • Eye of Bahamut is your way to inflict all of your debuffs, most notably Doom - Chaos. This will break the enemy after any turn they take. This debuff only lasts 3T, so once it falls off, consider using Eye of Bahamut again. You can also use it in 3 target fights for the damage if you're in force time.

  • Inferno recharges in 3 skill uses, and delays all enemies + launches them. Use it whenever it’s up!

  • Caius's BT effect can really push enemies back relentlessly, and all you need is for any of his debuffs to applied! You can really abuse this by using his BT+ into BT, but this is only recommended if your strategy is built to support it, as you'd effectively be sacrificing his 1 phase of BT+ auras for 6T of break delay.

  • Set Doom Crush is great when you don’t want to take a damage turn off to apply to Doom with S2.
