Com2uS announced on the 21st that it is celebrating the 12th anniversary of 'Summoners War: Sky Arena' with the return of the 'Hero Dungeon Returns' event. This anniversary update is scheduled to run for a total of 10 weeks, lasting until June 28.

Dubbed the '12th Anniversary My Own Hero Dungeon Returns,' this event boasts the largest lineup in history, featuring 144 different monsters, including those added since the 11th anniversary. Participants are free to pick one monster per week, regardless of their attribute, to unlock a dungeon and earn the monster as a completion reward. You will be able to select a total of 10 monsters throughout the event.

If you manage to clear all 10 floors of your chosen dungeon for the week, you will receive 250 summoning pieces, enough to summon up to five of those monsters. Clearing at least five floors each week nets you three Mystical Scrolls, with a grand total of up to 30 scrolls up for grabs during the event. Furthermore, special rewards like 12th Anniversary Light & Dark scrolls, additional Mystical Scrolls, and Devilmons are handed out based on your cumulative floor clear count.

Meanwhile, to mark its 12th anniversary, Summoners War has been rolling out growth opportunities, such as events allowing you to obtain natural 5-star monsters with fully enhanced skills and support for skill level-ups. The game has also introduced quality-of-life additions like the 'Summon Mileage System' and 'Special Missions.' Com2uS plans to continue the 12th-anniversary festivities with the Hero Dungeon Returns event and a variety of other engaging content.
