Скачать или смотреть Main DPS Chen Qianyu Damage Showcase (No Food Buffs)

I'm too broke to PayPal Perlica 30k, so I've been running Rhodagn's pockets. Total damage, build rationale, and skill rotation for the Chen Qian-NUKE further down the description.

Just a quick video showing how high Chen's damage can go if you treat her like a hypercarry. You can definitely squeeze in more damage with some adjustments and a lot more investments.
To be completely fair, if someone's crazy enough to do the damage & stagger calcs, and find the best route, most of the 1.0 roster can reach this level of damage... probably.

TOTAL DAMAGE:
If you add everything up from the first hit of Chen's Finisher to the last hit of her Ult, she did 73,232 + 306,064 + 33,354 + 34,499 + 35,644 + 35,644 + 35,644 + 35,644 + 450,174 = 1,039,899 damage to Rhodagn in the course of 7-8 seconds.

GEAR RATIONALE:
Chen (Sundering Steel, Bonekrusha set with off-set Swordmancer TAC Fists)
Just ATK% and DMG% stacking. I focused on Chen's Ult damage since the final hit deals 1125% at Mastery 3 for a P3 Chen. Basic Attack's also at M3 because it results in a 900% Finisher that gets a further 175% boost against staggered bosses.
Akekuri (Fortmaker, Frontiers set with off-set Eternal Xiranite Gloves)
Akekuri gives a good amount of team buffs (Link, ATK% during Ult at P3, DMG% with Frontiers), provides more SP to allow the Battle Skill spam, and frees up Frontiers off of Pog. The set just maximizes her Int to 500 without needing too much investment. Alternatively, you can level & promote her and artifice her gear to let her use Thermite Cutter.
Pogranichnik (Thermite Cutter, Pulser Labs set with off-set LYNX Gloves)
Arts Intensity increases the DMG% Taken debuff Breach applies and Pulser Labs/Hot Work gives the most of it while allowing Pog to wield Thermite Cutter/Never Rest instead of Fortmaker (though he honestly can do that in this team). Mastery 1 on his Battle Skill and Ult are required to easily activate his talent and give Chen a further 24% ATK Boost when she triggers a Steel Oath charge up to 3 times.
Lifeng (Chimeric Justice, Eternal Xiranite set with off-set Bonekrusha Heavy Armor)
Ult Gain Efficiency focus while giving Lifeng another team DMG% buff with Eternal Xiranite on top of the Phys Susceptibility and Link he provides. This allows me to stack Vulnerability without using up SP.

ROTATION:
Starting from Rhodagn Phase 2 (with carry-over Breach debuff to trigger Lifeng's Combo. Final Strike also noted because the stagger and it being part of Lifeng's Combo trigger is important)
Lifeng Ult - Chen Final Strike - Chen Combo - Lifeng Combo - Chen Final Strike - Chen Battle Skill (timed to interrupt Rhodagn) - Pog Battle Skill (Full Breach) - Chen Final Strike (Stagger Node triggers) - Pog Combo - Akekuri Combo - Chen Final Strike (make sure Lifeng's Combo is still on cooldown) - Pog Ult - Lifeng Battle Skill (Phys Susceptibility and to trigger Chen's Combo Skill before his own) - Chen Final Strike (delay if necessary) - Chen Battle Skill - Chen Combo - Chen Battle Skill (Stagger triggers) - Chen Finisher - Akekuri Ult - Lifeng Combo - Chen Ult

Again, anyone can still improve this. My shoddy damage calc-ing led me to 478,588 and 551,770 on just the last hits of her Finisher and Ult, respectively, but that requires P5 on Sundering Steel, Never Rest on Pog, and Thermite Cutter on Akekuri, Gear artificing on the three supports' relevant stats, P1 Lifeng with M3 Battle Skill, and multiple crimes against humanity... Still no food buffs though.

Even with all this, I can't recommend Hypercarry Chen. The reason the showcase is on Rhodagn aside from him being the easiest boss is because you're gimping everyone's damage, even Chen, for the big Finisher and Ult numbers. Against the first phase of the Marble Aggelomoirai, you'll take forever killing the tentacles because they never stagger and this hypercarry build relies on way too many buffs to do damage.
