The newest hero for Seven Knights Re:BIRTH (hereafter SKRB), Diao Chan, can be acquired for 5,000 'Glory Coins'—the guild war currency—just like Amelia before her. She is built specifically for guild skirmishes, boasting a kit tailored for 3-on-3 combat. Recently, however, she has been the subject of some intriguing discourse: players are starting to whisper that she might actually hold her own in the 'All-Out War' mode. Let’s dig into the details.

Q. What kind of hero is Diao Chan?
A. She’s a support who keeps her team ticking with heals and buffs, while keeping the opposition in check with debuffs, including a rather pesky sleep effect.

Diao Chan’s kit is focused; she hits fewer targets but packs more utility. Her basic attack heals the ally with the lowest HP, and upgrading the skill bumps that recovery by 1 percentage point.

Her skill, 'Marching Song,' provides instant healing for three allies. At 2-transcendence, things get spicy: if the healed allies are of the Attack or Magic types, their skill cooldowns are reset—though Diao Chan herself is excluded. In a 3-unit guild war, this is a guaranteed reset, while in larger PvP modes, you'll be relying on a bit of RNG.

'Song of Protection' hits three enemies with an 85% chance of a 2-turn sleep, plus a guaranteed 2-turn reduction on their turn-based buffs. It also grants two allies (excluding herself) a 47% boost to critical damage for 4 turns. Once upgraded, the sleep chance hits 100%, and the buff grants two allies a 30% boost to all attack power for 4 turns. Reach 6-transcendence, and you’ll also slap a 78% reduced healing received debuff on enemies for 3 turns.

Her passive, 'Smile of the Moon,' is where the real magic happens. Diao Chan gains an 'Effect Accuracy' buff that scales with her max HP—5% per 1,000 HP, capping at 45% once she hits 9,000 HP. She also gains a shield equal to 39% of her max HP once per round for 3 turns. If the two other allies are Attack or Magic types, her basic attacks grant them an HP-proportional shield and a 2-turn crowd control immunity. Upgrading the skill pushes the shield value from 39% to 45%, and the allies’ shield buff from 20% to 22%.

Q. What are the key buffs and debuffs for Diao Chan?
A. Cooldown resets, shields, crowd control immunity, and sleep.

Diao Chan’s utility revolves around those cooldown resets, shields, CC immunity, and sleep. The CC immunity and shields are absolute lifesavers for your squishier Attack and Magic heroes. Because these effects trigger via her basic attacks, you can effectively treat them as permanent buffs. In a PvP meta saturated with crowd control, this is your primary tool for breaking through the enemy’s interference.

The sleep effect is the ultimate tactical disruptor, breaking the opponent's planned skill rotations. With the 100% upgrade and her 45% passive bonus to effect accuracy, you’ll likely land that sleep consistently, unless your opponent has stacked a ridiculous amount of effect resistance.

Q. How should I set up her gear?
A. Focus on a Paladin set based on HP, and pile on the survivability stats.

Diao Chan’s gear is all about HP. She’s a support, so don’t waste slots on offensive stats. Build around the 'Paladin' set for the HP bonus, then prioritize 'HP (%)', speed, 'Damage Received Reduction', and 'Block Rate'.

Defense (%) is another solid choice for the remaining slots. Even in a meta where 'Defense Penetration' is everywhere, it’s still a crucial stat for staying alive. While you only need 9,000 HP to max out her passive, her healing is also tied to her max health, so more is always better. As for Effect Accuracy, don't worry about it—her passive handles that entirely.
