The 15th Dracanian Anniversary Festival began on 10 September 2026 and is scheduled through 10 October 2026. The official article lists the bonus code DSO15BDAY, anniversary weapon upgrades, the Lucky Pass and festival chest rewards.
Prioritize limited-time rewards first, then decide whether any paid pass or shop bundle is worth it for your account. Do not buy around a single event unless you already understand how often you will keep playing.
