Defense Derby, a real-time strategy defense mobile game developed by RisingWings, an independent studio of KRAFTON, Inc., has released its first update on September 4, 2023. The update brings a new unit, new modes, new rewards, and balance adjustments to the game.
Meet the Plaguemancer
The highlight of the update is the introduction of a new unit called the Plaguemancer, a magic-type unit of the beast faction. The Plaguemancer has a special ability called Plague Time, which allows him to infect his enemies with a deadly disease that deals damage over time.

Infection damage from the Plague Time skill increases proportionally to his attack power, so he becomes more powerful as he’s leveled up. The Plaguemancer can also spread his infection to nearby enemies when he dies, making him a formidable foe on the battlefield.
The Plaguemancer is a rare unit that can be obtained through various ways such as:
- Logging into the game for 7 days during the Curing Swamp season
- Purchasing from the Shop of Blessings
- Participating in the Lucky Draw
- Winning in the Derby Brawl – Plaguemancer Mirror Match mode
New Modes: Derby Brawl and Random Hero
To celebrate the release of the new unit, a new mode called Derby Brawl – Plaguemancer Mirror Match has been added. In this mode, everyone starts with the same deck that includes the Plaguemancer. The mode will be available until September 14.
A new Themed Mode, Random Hero Mode, has also been added. In this mode, players assemble their deck with units, artifacts, and castle skins while the hero is randomly selected when the battle begins. This allows players to enjoy the unique experience of scouting and assembling their deck with various units that pair best with the randomly selected hero. The Random Hero Mode will be available from September 15 to September 28.
New Rewards: Season Check-in, Shop of Blessings, and Lucky Draw
With the beginning of the Curing Swamp season, the Season Check-in, Shop of Blessings, and Lucky Draw have been updated. Players can receive 1,000 Cubics, 24 hours of Gold, and 24 hours of Elixir by logging into the game.
Depending on the number of log-in days, players can earn various rewards such as Crystals, Plaguemancer Emotes, and if they log in for 7 days, a Rare Plaguemancer card.
The Plaguemancer can also be obtained through the Shop of Blessings and the Lucky Draw.

- Added Unique Faction Bonus to the Derby Mode
