Zhao entered the TOPS records hall with the calm of someone who had already read the fine print twice. As an Ice Defense agent of the Krampus Compliance Authority, her work was to investigate companies inside TOPS and make sure regulations were not treated like decorative suggestions. Dialyn called her 'the Unbeaten Legend', a title that fit her business savvy and unwavering integrity. In combat, that same temperament showed up as patience: Zhao did not rush the field. She let Frostbite gather, then stepped in when the squad needed a shield, a heal, and a very precise increase in damage.

The HP Threshold: A Lighthouse for CRIT

By 2026, Zhao's debut banner, Priceless Heart, had already closed. It ran in Version 2.5 from December 30, 2025 to February 5, 2026, so newer players meet her through reruns, accounts, or the long shadow she casts on defensive team building. The community snapshot at launch was warm: an 8.1/10 score from 11 votes. That number made sense once players understood her central demand. Zhao wants HP, and she wants enough of it to turn her Core Passive into a team-wide damage instrument.

The key number is 27,000 HP. Zhao needs that much to maximize the CRIT Rate buff from her Core Passive. It is not a hard requirement for every squad, but approaching the threshold sharpens the whole team's output. Her HP threshold works like a lighthouse lens: the closer the squad gets to 27,000 HP, the clearer every CRIT signal becomes.

Field note	Recommendation
Core stat target	Build toward 27,000 HP to maximize the Core Passive CRIT Rate buff
Build path	Full-HP for the strongest damage buffs; splash Energy Regen or CRIT DMG for smoother play
Additional Ability	Active with an Attack, Anomaly, or Support teammate; Ether Veil: Wellspring buffs scale from Zhao's max HP
Team role	Defensive support who converts survivability into offense
Community snapshot	8.1/10 from 11 votes at debut

A full-HP build is the cleanest expression of Zhao's kit. It pushes her team buffs as high as they can go and keeps her personal contribution honest. A mixed build with Energy Regen or CRIT DMG is not wrong; it simply trades ceiling for comfort. The important thing is not to treat 27,000 HP like a magic gate. It is a target, a direction, and a promise that Zhao's defensive work will also make the scoreboard uncomfortable for the enemy.

Frostbite and the Wellspring Rhythm

Zhao's combat loop is built on a resource called Frostbite. She accumulates it whenever an on-field Agent deals damage, and she also gains it through her EX Special Attack, Chain Attack, and Ultimate. Frostbite gathers the way a ledger gathers signatures: small, routine entries that suddenly add up to authority. Once the gauge is full, the squad calls Zhao in to activate Entry Skill: Burst of Frost. The entry deals damage and activates Ether Veil: Wellspring. The squad receives additional buffs, and a Quick Assist can trigger.

Her EX Special Attack is the other half of the rhythm. Zhao performs a series of slashes while consuming a portion of her HP, and she gives squadmates a continuous health recovery effect. Under Ether Veil: Wellspring, the EX Special Attack can also trigger a Quick Assist. That exchange is the heart of her playstyle: spend health, return health, and keep the team's momentum from stalling. She is not a healer in the conventional sense. She is a compliance officer for bad situations, arriving with paperwork, ice, and a correction.

Best Teams: Attack First, Anomaly Second

Zhao is best used on an Attack team. Her Ether Veil benefits Ye Shunguang the most because it helps accumulate Qingming Sword Force stacks. She also fits naturally beside Billy and Nicole, where her buffs can raise Billy's overall damage while Nicole handles the usual support chores. The squad does not need to force Zhao into the main damage slot. Her job is to make the main damage dealer look inevitable.

She can also work in Anomaly teams because her kit buffs an ally's ATK and DMG. Two Anomaly units are usually the best pairing, since the result can produce high Disorder damage. Any combination can work, but their Additional Abilities should be checked before the team leaves the planning screen. Bangboo choice should patch the team's role, not its personality: defensive or support utility for Attack squads, anomaly-flavored help for Disorder setups.

W-Engines, Drive Discs, and Skill Priority

W-Engine ratings for Zhao are measured at Update Level 0, so the safest reading is to favor options that reinforce her HP-scaling support identity. HP substats, defensive utility, and energy comfort all matter more than raw personal damage. Drive Discs should follow the same logic: HP-first main stats, then Energy Regen or CRIT DMG where the team needs a smoother loop.

Skill priority should respect the loop rather than the menu order:

Priority	Skill	Why it matters
1	Core Passive	Converts HP into CRIT Rate and damage bonus; this is Zhao's engine
2	Entry Skill and EX Special	Drives Burst of Frost, Ether Veil: Wellspring, healing, and Quick Assists
3	Additional Ability	Turns max HP into team buffs when the right ally types are present
4	Chain Attack and Ultimate	Useful Frostbite sources and burst windows, but secondary to the support loop

Materials, Mindscapes, and 2026 Context

Her material checklist follows the familiar agent pattern: ascension resources, core skill chips, and the usual ice-and-defense-flavored set. Mindscape Cinema investment is a question of ceiling rather than entry. Early copies smooth her Frostbite flow and buffs; later copies raise the ceiling, but they are not required to make the 27,000 HP target meaningful.

When the TOPS audit finally ended, Zhao closed her ledger and stepped back into the field. Swapping into her felt less like a tag-in and more like a clockmaker seating a final gear; the whole team's rhythm clicked. That is the Zhao story in 2026: a defense agent who makes survival look like a strategic advantage, and a legend who remains unbeaten because she never lets the fine print go unread.
