Yungeon, introduced in Seven Knights Re:BIRTH, is a Magic-type hero who functions as a main DPS capable of clearing the battlefield on his own with AoE attacks and high survivability. Right after his release, he showcased enough firepower to reshape the Arena meta, cementing his position as the new starter for Magic decks.

The core of his kit is his passive skill, Bureaucrat of Shinji. Awakened Yungeon gains Blessing, ensuring single-instance damage never exceeds 25% of his maximum HP, while also gaining a shield equal to 185% of his Magic Attack. On top of that, his Critical Hit Rate and Weakness Attack Rate both increase by 50%, making his gear optimization relatively forgiving.

His survivability ramps up significantly when paired with three or more Magic-type heroes. He gains 1 stack of All Damage Immunity per basic attack and 2 stacks per skill cast, stacking up to 6 times. When struck by crowd control, he cleanses all debuffs once per battle and gains CC immunity for 2 turns. Therefore, team compositions featuring at least three Magic units are strongly recommended when using Yungeon.

He also features an effect that inflicts additional Piercing damage on 3 enemies every two attacks. Because this damage scales not only with his Magic Attack but also with the target's maximum HP, it is especially useful for stripping Damage Immunity and wearing down high-HP Defense deck heroes.

Among his active skills, Rapid Fire stands out the most. It converts all enemies' HP to 39% and then deals 3 hits of Piercing damage that scale higher as the target's current HP increases. Against targets with 50% or higher current HP, it has a 40% chance to inflict Aura—a new crowd control effect—for 2 turns. Enemies afflicted by Aura cannot act and take additional Fixed Damage equal to 15% of Yungeon's Attack whenever they are hit by an attack.

Ten-Shot Cannon attacks 4 enemies and removes 2 buffs. While it cannot strip Damage Immunity, All Damage Immunity, or Might, stripping standard buffs helps pave the way for follow-up attacks. His Awakening skill, Volley Fire, targets all enemies with Aura while dealing 65% Defense-ignoring damage, serving as a reliable finisher.

Yungeon reaches full potential at 6-Transcendence. When he scores a kill with Ten-Shot Cannon, it triggers Rapid Fire at 70% power; when he scores a kill with Rapid Fire, it triggers Ten-Shot Cannon, up to once continuously. Securing just a single kill through HP conversion and AoE attacks triggers a secondary skill activation, instantly flipping momentum in your favor.

Yungeon's primary battleground is PvP content. With Rapid Fire's HP conversion, he first lowers the enemy's high health, then pierces through survival effects with Defense-ignoring and Piercing attacks. At 6-Transcendence, scoring a kill with a skill hit triggers chain attacks, completely turning the tide of battle in an instant.

When facing Offense decks and Magic decks, Blessing and Damage Immunity are crucial. They allow him to withstand powerful enemy attacks, convert health with Rapid Fire, and exhaust the enemy's Might and Damage Immunity through subsequent AoE attacks. Landing Aura can also completely lock down enemy heroes.

Against Defense decks, HP conversion and max-HP-proportional bonus damage truly shine. After reducing the high-sustain Defense deck's health to 39%, he unleashes massive firepower with Defense-ignoring attacks and buff cleanses. Showing flaw-free performance in PvP, Yungeon boasts a strong presence not only in the Arena but also in Advanced Arena, All-Out War, and Guild War.

Note that depending on his growth status, he also performs exceptionally well as a fodder-farming hero. If existing fodder farmers like Freya, Omok, or Lu Bu fall short in stats, considering Yungeon is a solid option.

When placing Yungeon in a traditional Magic deck, a lineup built around Skuld, Dongyeong, and Reginleif is standard. Players typically flex in Omok, Yeonhee, or Melkir to round out the squad. This naturally satisfies the requirement of 3 or more Magic-type units, enabling both Yungeon's Damage Immunity stacking and debuff cleanse. Meanwhile, Freya, who previously anchored Magic decks, has seen her priority drop.

A 5-Magic-hero deck focuses heavily on Speed to secure the first attack, following up with a skill combo between Skuld and Yungeon. Speed has traditionally been vital for Magic decks, and with Yungeon joining a stellar Speed utility hero like Skuld, there is no reason to forfeit the first strike. Naturally, depending on accessory availability, builds focused on core durability are also viable.

A hybrid composition featuring Sunran, Yungeon, Dongyeong, Carl Heron, and Orca is another strong choice, often referred to as a 'Yungeon Offense Deck'. Because this lineup fails to meet the 3-Magic-hero requirement, Yungeon cannot utilize his Damage Immunity stacking or debuff cleanse. However, he still retains Blessing, shields, innate Crit/Weakness Attack buffs, HP conversion, and 6-Transcendence chain attacks, ensuring firepower remains potent. Pairing Sunran and Yungeon with strong support heroes makes this setup a frequent sight in the Arena.

Additionally, in All-Out War, splitting Magic decks centered around Yungeon has become a popular trend. It is sometimes used as a substitute for Instant Death starting from Rare tier. Here, one Magic team centers around Freya, while Team 2 featuring Yungeon pairs him with Yeonhee, Skuld, Melia, and Juri. This composition highlights Juri's revival prevention, Yungeon's raw firepower, and Skuld's utility.

For equipment, players typically choose between the Tracker and Assassin sets. Thanks to his passive providing +27% Critical Hit Rate and +32% Weakness Attack Rate base—both jumping to 50% upon Awakening—Yungeon offers flexible gearing. At 2-Transcendence, Skills 1 and 2 gain 40% Defense-ignoring damage, making the Assassin set a great fit. His Awakening skill also carries a one-time 65% Defense ignore.

However, you don't necessarily have to insist on Assassin. Depending on substats, a Tracker set can perform almost as efficiently. Ultimately, choose between Assassin and Tracker based on team composition, Speed priority, and gear substats. Aim to hit 100% Critical Hit Rate and Weakness Attack Rate including his passive, and stack Critical Damage and All Attack % if possible.

Additionally, All Attack %, Effect Resistance, and Effect Hit Rate are valuable stats, so maximizing them through substats is recommended. In extreme Speed Magic decks, focusing heavily on Speed means giving up some other options, while hybrid builds with Sunran tend to favor utility stats like Effect Hit Rate and Effect Resistance over pure Speed.

For Exclusive Gear Tuning, Shatter is the top choice to boost firepower against Defense decks. If an extreme Speed build leaves your Critical Damage lacking, Damage Amplification works well, while Effect Hit Rate is viable against high-Effect Resistance Offense/Magic decks to ensure Ten-Shot Cannon's buff removal and Aura hit.

Transcendence targets are clear depending on your goals. At 2-Transcendence, 40% Defense ignore is added to Ten-Shot Cannon and Rapid Fire, making it the minimum requirement for PvE and secondary All-Out War teams. Even at low Transcendence, core mechanics like HP conversion, Aura, and Blessing are functional, allowing immediate deployment.

However, if you plan to make Yungeon your Arena starter, 6-Transcendence is extremely important. The continuous skill activations following a kill complete his AoE carry power. Because the performance gap between 2-Transcendence and 6-Transcendence is so noticeable, aiming for 6-Transcendence is highly recommended.

In summary, Yungeon is a high-priority main DPS pull for anyone running a Magic deck. If your focus is PvE and All-Out War, stopping at 2-Transcendence is an option, but for Arena starters, securing 6-Transcendence during the pickup event is recommended. Even if you do not run Magic decks, considering his fit in Sunran hybrid builds and various PvE roles, acquiring as much Transcendence as possible during this banner is well worth it.
