Use Battle Skills to Interrupt Attacks
Triaggelos will be very aggressive with charge-up attacks right from the start. You can interrupt these attacks by using Battle Skills when you see the red circles around the boss.
Dodge the Meteors
Triaggelos will float up higher in the air and summon meteors towards your characters. Triaggelos cannot be hit while he's up in the air, so do your best to dodge the meteors.
This attack will be upgraded in Phase 2, where the meteors can unleash shockwaves after landing. You can jump over the shockwaves to avoid the attacks.
Go to the Yellow Barrier
During Phase 2 of the fight, Triaggelos will charge up and unleash a powerful attack. Head to the Originium branch so that its yellow barrier can shield you from the attack.
Defeat the Small Enemies to Remove Barrier
Triaggelos will summon a Barrier during Phase 2 to protect itself then summon smaller enemies. Defeat the enemies to remove the barrier and keep fighting Triaggelos.
Stay Away From Rock Pillars
While fighting the smaller enemies, rock pillars will begin to form around the arena. Try to avoid getting to these formations as you will receive damage if you get too close.
Break Invisibility with Attacks
During phase 3, Triaggelos will begin to cloak itself while favoring ranged attacks. Attack Triaggelos to break its invisibility and continue your offense.
You can determine the boss's location by looking for the purple haze it is surrounded by while it is invisible.
