Triaggellos is one of those Arknights: Endfield bosses that looks simple until you're two minutes in and your cooldowns are a mess. If you're still gearing up or swapping teams on the fly, having reliable Arknights endfield accounts can make practice runs less painful, but the real win comes from reading its three-element rhythm and saving your biggest damage for the stun windows.



Red Phase: Interrupt First, Dodge Second
In the red phase, the boss throws out Glowing Rocks right away. Don't panic—just step out or dodge and keep your camera steady so you don't lose track of its body tells. The real threat is the red pulse circle around it, because that's the "big hit is loading" sign. A lot of players back off here, but it's usually better to shut it down. Use skills on 1, 2, 3, and 4, or fire a Character Assist with E to interrupt and build stun instead of eating the attack. Watch for that red glow before the Slamdown as well; it's quick, and missing the cue gets you flattened. Once the stun finally lands, don't get cute—stack Ultimates and Signature Abilities together and burn hard while it can't move.



Green Phase: Survive the Script, Then Clean Up
Green phase is the awkward one because Triaggellos goes invulnerable and tries to force you into a little survival routine. When Anchor Shockwave starts, you need to hug the Originium Saplings or you'll get blasted. After that, adds show up and the boss starts planting spikes into the ground. It's tempting to sprint around, but that's how you run straight into marked zones. Pull the small mobs toward you, clear them fast, and keep your dodges for when you're boxed in. Then come the rocks again, except now they kick out shockwaves you'll need to jump over. When the boss drops invuln and opens back up, it's not doing the heavy red-circle charge, so just dump whatever skills are available and keep pressure on.



Purple Phase: Keep Moving, Punish the Laser
Purple phase looks scary because Triaggellos fades out or takes on that eerie glow, but it's often the cleanest section if you stay calm. Missiles will keep raining down, so read the floor, follow the red markers, and keep drifting toward open space. There's almost always a safe pocket, even when it feels like the whole arena is lit up. Keep tagging it with hits and it'll drop the stealth sooner than you'd expect. The key moment is the Laser Beam: you'll see a red line draw on the ground, and that's your warning to sidestep or get behind it right now. Once the laser fires, it's stuck facing one direction, so you get a free damage window to close the fight.
