Train No.7 Raid Guide: All 11 Bosses and Phase Mechanics

How the raid is built

Train No.7 is the final test's high-difficulty team dungeon, aimed at players who have already learned the combat system. It contains 11 bosses, and its phase goals are explicit: break a shield, kill before a timer, survive a mechanic that can delete the group. The eleven include the fixed phase fights and the rotating candidates; every boss with a published final-test mechanic is covered below. The train is a sequence, but not a straight line. A fixed opening and a fixed Yuan Tao finale sit around a weekly rotating pair, which is why a route that worked last week can fail this one.

Two habits decide most pulls. The first is resource discipline: awakenings are not free, and the opening of the raid is designed to make you spend them early. The second is assignment: every lethal mechanic in the raid asks a specific player to do a specific job, and a group that improvises will usually assign the same job to nobody. If you are new to the raid, farm Area Investigation first to learn your character's recovery and shield-break timing; Train No.7 assumes both.

Shield breaks are the through-line. White shields do not fall to raw damage; they fall to the right route, and the combat system explains the guard-break and throw logic behind that. Once the shield is down, the timed kill begins, and every damage cooldown you saved is now worth double. The artifact guide covers the loadout pieces that make those windows count.

The phase route at a glance

Phase 1: skip the first awakening, spend everything on He Yuchen

The opening mob is a resource test, not a boss. Kill it quickly and do not use your awakening skill. The mob dies to ordinary pressure, and the awakening you save is the burst you need on He Yuchen. Groups that open with a cinematic spend the next two minutes paying for it.

He Yuchen is the opposite instruction: full burst, no holding back. His fight is where the saved cooldowns go. The mechanics are manageable if the group reads two tells. Lightning attacks stack a vulnerability and fire attacks stack a burn, so track both debuffs. When He Yuchen charges in the center and produces ball lightning, let the ball hit a player. That hit grants a double-damage buff. Do not let the ball reach He Yuchen, because that heals him and undoes the burst window. When he discharges orbs, eat them; dodge the small skills normally. The phase is a damage race with a self-inflicted healing trap.

Phase 2: the fat boss and the two shields

The fat boss opens with a grab. Bait it: one player draws the grab, then dodges, and the group stays off the bait. A clean opening keeps the healer's resources for the shields.

There are two shield breaks, and they are not the same instruction:

The eye marker is a targeted lethal mechanic with a heal attached: leave the stack before the cast completes. If the marked player is the healer, call it.

Phase 3: Yuan Tao and the four pillars

Yuan Tao starts invincible and reflects damage. Hitting him before the pillars fall is self-damage. Four pillars surround the arena, one per mini-boss, so the pillar phase compresses the earlier route.

Break the pillars simultaneously or near-simultaneously. Leave a few bars on each, stop damage, then finish them together; an early break gives Yuan Tao a window. Assign one player or pair per pillar and hold the last sliver until the countdown.

Dodge the wires while you do this. They force movement exactly when a player must stand still to catch. Once the pillars are down, Yuan Tao becomes attackable; switch to full damage, but keep handling orbs and wires.

True Yuan Tao: the final-test movement change

Yuan Tao's defeat leads directly into True Yuan Tao. This is the longest mechanic list in the raid, and the final test added one change that breaks the old guide route.

The change is simple and brutal: True Yuan Tao moves, and he follows one squad member. He is no longer a fixed landmark. The old advice to stand behind him and DPS no longer works as written, because the cover moves with him. The group has to track which player he is following and reposition the hiding line continuously. Assign that player to call his movement, and do not assume last week's safe spot is still safe.

The fight rewards patience: break the colored artifacts before damaging the boss, keep chain assignments explicit, and treat the water orbs as a movement check. The phase ends when the mechanics are clean, not when the group outdamages them.

The 30% enrage and Wang Ye's formation

Every Train No.7 boss enrages below 30% HP. The answer is the same across the raid: save Wang Ye's formation for the enrage window, place it on the boss's startup, and interrupt the skill. A successful interrupt produces a 4-second stun, and the final test measured roughly 8% of the boss's HP of damage inside that stun. That is the difference between a clean finish and a last-phase wipe.

Do not use the formation at the pull; it answers one problem, and the problem starts at 30%. Protect Wang Ye in the last phase and call the formation before the boss commits. The Wang Ye guide covers the formation states, the 3A cancel, and the placement habits that make the stun reliable.

The weekly rotating pair and their counters

Two named bosses rotate in each week. Learn each counter rather than one route. He Yuchen also anchors phase 1, so his orb rule is worth learning even when he is not in the pair.

The rotation changes the order of the work, not the fundamentals. A group that knows the counters can clear either pair; a group that learned one script will spend the first two pulls of the week re-learning the fight. If you are pugging, ask which pair is active before the pull and assign the counter jobs in voice.

Team roles, voice chat and the pug problem

The raid is a four-player fight with practical roles. Most groups bring one healer or support, one Wang Ye for the enrage formation, and two damage dealers. The healer owns the phase 2 qi-source skill and the phase 3 orb catches; Wang Ye owns the last 30%; the damage dealers hold cooldowns for the shield window rather than spending them on the approach.

Use external voice chat. In-game voice has known problems, and every lethal mechanic is a call: the eye marker, pillar countdown, orb catch, chain transfer and enrage formation. A group on external voice can assign those in one sentence; a group typing cannot.

Pug groups should not start with Yuan Tao. Farm Area Investigation until recovery and shield-break timing are automatic. Yuan Tao's four pillars correspond to four mini-bosses, and the fight is hard without a group that has practiced the countdown. One strong player cannot carry the pillar break or the orb catches.

What you take out

Train No.7 is the endgame source of epic equipment blueprints, character breakthrough materials and set pieces. That makes it the natural next step after the weekly gates on the progression guide. If your group can clear the fixed phases but not the rotating pair, keep running the fixed route for blueprints and treat the pair as the stretch goal.

The raid is also where the artifact and inscription advice gets tested. A basic-attack package that looks strong in a dungeon can fall apart in a timed kill if the group does not hold burst for the shield window. Check the artifact guide for the loadout logic, and the dungeon guide for the other endgame loops that feed the same gear. The Abyss of Tao is a different test, covered on its own Abyss of Tao page.
