The final piece of the summer season — new boss Bellona
Nexon's MapleStory applied its third summer update on August 20, 2026 (client 1.2.418, Korean service), and the centerpiece is a new boss: Bellona (벨로나). She caps off this summer's "Overdrive" content season, extending the high-level endgame boss lineup by another tier.
Bellona is themed as a "cruel executioner," cast in the lore as an apostle of Gerne Darmoor — a figure of near-fanatical faith. The framing positions her as the narrative capstone of the summer season.
Entry requirements and party size
| Detail | Info |
|---|---|
| Patch date | August 20, 2026 (client 1.2.418) |
| Entry level | 280+ |
| Prerequisite | Pre-quest completion required |
| Difficulties | Easy · Normal · Hard |
| Party size | Up to 3 players |
| Concept | Cruel executioner, apostle of Gerne Darmoor |
Bellona is a high-level boss that Level 280+ characters can challenge after finishing a pre-quest. Parties of up to three are allowed, a design that targets both solo spec checks and small-group clears.
Rewards — a new radiant boss accessory
Defeating Bellona yields a new radiant boss accessory — localized here as "Starving Blood-Red Spirit" (굶주리는 핏빛 원혼) — alongside items such as the "Madness Eternel Armor Box" (광기의 에테르넬 방어구 상자). Radiant boss accessories have long served as core endgame progression pieces, so the new accessory is likely to become an immediate target for high-level players chasing stat gains.
| Reward | Role |
|---|---|
| Radiant accessory "Starving Blood-Red Spirit" | New endgame accessory |
| Madness Eternel Armor Box | Armor progression material |
The armor box is a growth currency used to complete and upgrade high-tier armor sets. Because a single boss drops both a new accessory and armor material, players can optimize their weekly boss crystal income and stat-up route together.
Closing out the "Overdrive" summer season
Bellona's arrival isn't a one-off patch — it's the terminus of this summer's "Overdrive" season roadmap. The season opened with the reveal of new class Lethe (레테) and expanded through sequential updates. Bellona lands as the final step, giving characters who grew over the summer an endgame target to aim at.
Seasonal roadmaps are a strategy for seeding progression motivation across the window when new and returning players flow in. This class → growth event → endgame boss cadence follows that template closely.
The August 27 first-clear race
The update also builds in a competitive hook. A solo first-clear race for Bellona begins August 27, 2026 at 7:00 PM KST. Races to the earliest clear are a device for drawing in high-spec players and driving community buzz.
First-clear events demand both spec and execution. Since this is a Level 280 boss, finishing the pre-quest and tightening your damage rotation ahead of time pays off.
Community reaction and what to watch
Among high-level players, the main talking points are the practical performance of the new "Starving Blood-Red Spirit" accessory and the reward gap between difficulties. Where Hard's required spec and drop efficiency settle could reshuffle weekly boss routes. Easy and Normal, meanwhile, lower the entry barrier to the new accessory, opening a stat-up path for mid-to-upper-tier players.
That said, the fine numbers — boss HP, phase mechanics, drop rates — are still settling as official notes and live play data accumulate. Early strategy info is subject to change, so confirmed figures are best updated later from verified data.
