Supplementary Notes to the Infographic Analysis:

The infographic covers the key critical points and should be reviewed prior to delving into the in-depth notes

Gameplay Notes:

  • Giga-Graviton isn’t tied to a buff, so you can use it as needed to instant break or push enemies back a turn. Prepare to generally use Eye of Bahamut on your free skill use.

  • Pulsar Burst is his go-to single target attack, and is used to upkeep his Guardian buff.

  • Eye of Bahamut is your way to inflict all of your debuffs. Timing Doom Chaos debuff expiration can be exceptionally strong vs certain bosses, or just great in any normal setting.

  • Inferno recharges in 3 skill uses, and delays just the targeted enemy, but it deals 50 CU (chase units) to all enemies, so you launch your target, and then you can launch the other enemy afterward if you want.

  • Set Doom Crush is great when you know an enemy is about to gain a lot of BRV and you don’t have your Doom Chaos debuff applied.

    • Make sure that Doom is NOT already applied. 2T Doom will not override to 1T Doom

    • Know that using Eye of Bahamut can reset your 1T debuff to 2T

Team Synergy Notes:

  • Caius operates fairly self sufficiently, just be careful of allies that inflict their own debuffs, and also which calls you use since those might also inflict more debuffs! Caius only leaves room for 2 others.

  • Caius’ calls are nice, as they apply all of his debuffs, and his LD call is great as it is a pocket AoE insta-break but only if the enemy does not already have 3 framed buff/debuffs, since Doom CHAOS won't be inflicted!


  • A sphere - ATK & BRV DMG are king. Note that he works with weakness damage triggered spheres now.

  • C sphere - Self healing triggers are good here. ATK is the best effect to look for (Garnet, Maria). Any aura effect would be considered best, or you can opt for a party battery sphere further below.

  • D sphere - Focus ATK aura, but mBRV is a mediocre option as well. Note that 3T buffing spheres are okay, but in the rare case you avoid his Pulsar Burst multiple turns, the effect may drop off and not be active for your EX skill.

Bad passives (if you lack enough CP to equip important passives):

  • BRV Attack HP Attacker +/++ Up (you almost never use BRV/HP+ variants with Caius with all of his skill uses)

  • DEF passives

  • Buff Speed Up (really shouldn’t be removed if you have Caius maxed)
