On March 19th, 'Seven Knights Re:BIRTH' (hereinafter referred to as SKRB) officially launched its collaboration event with the domestic IP 'Solo Leveling'. The update introduces limited-time heroes, dedicated equipment, exclusive content, and a new 'Surprise Raid' mechanic.

The heroes joining the fray from the Solo Leveling universe are Sung Jinwoo, Cha Hae-in, Yoo Jinho, and Lee Joohee. Sung Jinwoo and Cha Hae-in arrive as legendary-grade heroes, while Yoo Jinho and Lee Joohee hold rare status. Sung Jinwoo is a versatile magic-type unit, and Cha Hae-in comes equipped with unique abilities tailored for the Tower of Infinity and the Tower of Trials. You can secure these two through event rewards and the Wish Summon system.

As for the rare heroes, Yoo Jinho provides 'Silence Immunity', and Lee Joohee offers 'Bleed Immunity'. Both can be acquired by exchanging event currency in the event shop. Furthermore, Igris, the shadow soldier commanded by Sung Jinwoo in the original series, makes an appearance as a rare-grade pet. Its abilities include 'applying Boss Vulnerability to all enemies' and 'increasing all attack power for all allies'. The scenario event 'Hunter and Adventurer' is accessible to any player who has cleared stage 2-1 of the main adventure.

Beyond the heroes, do keep an eye on the collaboration gear. 'Sung Jinwoo's Coat' and 'Knight Killer & Baruka's Dagger' belong to the Assassin set, with armor primary stats boosting 'All Attack Power (%)' and weapon primary stats focusing on 'Critical Hit Chance'. 'Cha Hae-in's Combat Suit' and 'Cha Hae-in's Sword' are based on the Avenger set, where the armor grants 'All Attack Power (%)', and the weapon features 'Weak Point Attack Chance'. You can find the full breakdown of secondary stats in-game or via the official lounge.

The 'Surprise Raid' triggers with a certain probability after clearing levels 11-15 of the three standard raids. You will face exclusive bosses 'Leonid', 'Astraea', and 'Callistra', requiring a collective effort from all users. You will need a 'Surprise Raid Entry Ticket' to join the fight, which can be purchased up to 15 times each using Guild Coins and Honor, or 30 times with Rubies. The update also includes quality-of-life tweaks to tooltips and equipment display UI. You can find the nitty-gritty details in the official lounge notice.
