Light Tonatua: Mechanics and Counterplay
This section breaks down the core mechanics of the Boss Light Tonatua and outlines basic counterplay strategies. For a detailed, step-by-step execution guide, please proceed to the next section.
During the raid encounter, you need to keep the following seven points in mind:
- Void Dual Pact: Marks two players. After a short time, deals DMG and generates Spacetime Crystals at their current locations.
Guide：The two players must place the crystals in the center and at the edge of the arena to counter upcoming boss mechanics.
- Spacetime Field: Interact with the Spacetime Crystal to transform it into a Spacetime Field. Players inside are immune to projectile hits and take significantly less DMG.
Guide：When the boss unleashes a Spacetime Blast, follow the prompt to activate the crystal and stand in the field. On Hard-mode, the interacting player will also have to dodge a Void DMG zone. After dealing the Void DMG, relocate the zone to the edge of the battlefield.
- Purifying Light: Tonatiuh summons a one-hit Purifying Light that expands or contracts at a fixed speed.
Guide: Use the rim at the right moment to evade the light. On Nightmare mode, the boss summons three such lights, and players must teleport multiple times.
- Spacetime Collapse: Targets the current target holder and annihilates their space, dealing massive TIMS, drastically lowering aggro, and inflicting a long Vulnerable status.
Guide：The marked player must immediately activate defenses, and move to a safe area to hide. On Nightmare mode, the boss may also target and cover the safe area, and players are inflicted after being hit. Watch for combo attacks from the boss.
- End of Spacetime: Tonatiuh charges up and freezes time, releasing a decoying AoE explosion that knocks all players back, then tenuses the Radiant and Dark Crystals on both sides to pressure a devastating move.
Guide：Players must split into two groups under the side islands, use the explosion to push up them.
- Radiant and Dark Crystals: The Radiant and Dark Crystals continuously feed energy to the boss.
Guide：Both must be defeated simultaneously or they will regenerate. Breaking the crystals inflicts a matching elemental change. On Hard-mode, crystal have shields. Breaking them interrupts the boss's channel. On Nightmare, the players on the islands, and spawns a rift. Both teams must coordinate to destroy the crystal shields and rotate groups to avoid taking debuffs.
- Radiant Seed: Summon multiple Radiant Seeds that explode after a short time, instantly killing players within range. Players must move the Radiant Seeds.
Guide：Use rim to move the Radiant Seeds quickly and clear space for Allies.
Speedrun Guide of Dragon Shackle Raid（Light Tonatua）
Let's dive into the detailed walkthrough. By following this guide, you'll breeze through the encounter in under 3 minutes!
To begin with, as with other raids, you must split the team into two groups to handle the upcoming Light and Dark crystal mechanics.
Phase 1：The Portal Mechanics
The Light Dragon’s core mechanic is the portal system. Two marked players will drop portals—one at the edge of the arena and one in the center. Afterward, stack for the soil mechanic and prepare for the upcoming portal phase. When the dragon flies up and dives, open the portals to create safe zones and avoid being knocked back.
At least one player must also open the outer portal to create the second safe zone. Both portal users will receive a poison puddle—drop these at the top of the map and avoid using dash skills beforehand, as they slow you.
Next, a giant Lightbear appears. Use the portal to teleport past the barrier before it kills you. In Nightmare difficulty, everyone receives an AoE marker after porting, So, make sure you spread out to not stack these on top of each other.
Ads will spawn; group on the boss and use AoE abilities (e.g., Thunder Tempest or Marksman ultimate). Kill the ads quickly, as they hit hard.
The mechanic repeats. This time, the Lightbear moves from outside to center, so teleport outward using the middle portal. The tank will also receive a tank buster, so they must port last to avoid clipping others.
Phase 2：The Crystal Mechanics
At around 50%, the Crystal Island mechanic begins. The Light Dragon moves to the center and knocks everyone outward. Group 1 positions at the light crystals, and Group 2 prepares at the dark crystals. Your objective is to destroy both crystals at the same time, using the HP bar on the left to sync DPS.
On Hard or higher, each crystal gains a white barrier. After breaking it, you must teleport to the opposite side to hit the other crystal—failing to swap sides will kill you.
Once both crystals die simultaneously, the Light Dragon becomes staggered, giving you a prime DPS window. When jumping back down, use slow, controlled jumps (including double jump) to avoid falling off the map.
You’ll then face the crystal mech again. In Nightmare mode, you must teleport twice. The barrier first expands, so teleport inward; after resolving the mechanic, teleport from the inside back outward as it contracts.
Final Phase：The Explosion of Light Crystal
The last major mechanic is the Light Crystal Explosion. The boss summons six crystals that will detonate. Your goal is to use the teleporter to shift the middle crystals to one side, then slightly move the crystals on that side farther away. This creates a small safe zone in the center for DPS—stay tightly stacked.
After this, the fight becomes a straightforward DPS race. The boss repeats familiar mechanics, so just play safely and finish it off.
Conclusion
In conclusion, the battle against "Light Tonatiuh" is the ultimate test of a raid team's positioning skills. Adventurers must navigate through a barrage of AoE attacks and Area of Effect to find safe zones, all while seizing opportunities to defeat the dragon.
