In Brief:
- Nine Chronicles (official site) has switched on the Fenrir World Boss raid for the Odin chain, handing players a one-week season to chip away at a shared global HP pool.
- Access opens at Stage 50, with three complimentary tickets issued daily and a crystal entrance fee that scales with character level.
- Contribution now determines season payouts instead of a flat ranking split, and Fenrir’s rune table has been replaced by Legendary skill runes alongside Unique and Epic stat runes.
The Fenrir World Boss is now active on Odin, with the raid window opening while the chain’s Arena sits in off-season.
“Fenrir has arrived in Odin,” the team wrote in its announcement. “The World Boss means business and it’s up to you to bring him down.”

How the raid works
Every player on the chain attacks the same Fenrir health bar, since the wolf holds one global HP pool. Whatever damage a player deals in their own battle comes off that shared total. Once the boss is finally felled, a tougher version respawns and the cycle begins again.
A single run spans five waves, with the boss growing more dangerous the further players advance. Fights conclude with a battle grade that determines rewards, and the grades available are S, A, B, C and D.
To get in, players first need to clear Stage 50. Three tickets arrive daily — that is, every 7,200 blocks — and additional ones can be purchased with NCG. A crystal entrance fee also applies, scaled to the player’s character level.
A season covers one week, or 50,400 blocks, before a two-week off-season of 100,800 blocks begins. Because World Boss seasons are scheduled to occupy Arena off-seasons, Fenrir’s arrival coincided with the conclusion of Odin Arena Season 38.
What drops
The raid layers on four separate reward buckets. Battle rewards arrive as soon as a fight ends. Battle grade rewards trigger whenever a player climbs into a higher grade, and they reset with each new season. Boss kill rewards are handed to participants once Fenrir goes down, scaling with participation count and rank, while season rewards arrive at the finish.
Planetarium has shifted the season payout away from a pure ranking split. Distribution is now based on how much each player contributed, and players claim their rewards individually across the two-week off-season rather than receiving one bulk drop after the season.
Rank still matters at the top of the table. Anyone placing between first and 100th earns Golden Dust and AP Potions in addition to Rune Shards and Crystals, with the exact amounts tied to rank group and detailed in the game’s World Boss rewards tab.
Rune table swapped
Legendary skill runes plus Unique and Epic stat runes have taken the place of the reward runes previously tied to Fenrir and Saehrimnir. Those older runes are still available via Summon, then Rune Summon, and remain tradable through the shop on the PC client.
According to the team, the plan is to keep content value in check by rotating reward runes regularly through seasonal changes, working alongside the community.
Several other adjustments to the mode had already piled up in earlier release notes. The six World Boss runes — three for Fenrir and three for Saehrimnir — received an upward stat balance pass, though skill effects were untouched. Rune enhancement success rates were pushed to 100% across the board, and a Rune Level Bonus system now grants stat bonuses to equipped runes according to total rune level, spanning 30% to 1000%.
Thorns skill damage on certain Legend armor and world boss runes has been limited to 200,000 per hit. Developers also squashed a bug that prevented season reward claims while a Fenrir-type World Boss was running.
There’s a separate encounter for Heimdall players: Saehrimnir was announced for that chain, which likewise just saw Arena Season 22 come to a close.
Background
Fenrir originally served as the monster wolf of World 4. The game’s lore holds that after his defeat, his soul tumbled into the bottomless abyss of Ginnungagap, where the void’s dark energy consumed it — leaving him neither living nor dead and robbed of any will of his own.
Planetarium’s release cadence has been consistent throughout the year. Its v200450 update shipped June 25 at 11 a.m. KST, bringing 30 new stages numbered 471 through 500, Grade 8 Transcendence equipment, fresh Collections, and new items and active skills.
June 11 saw YGG Play and Planetarium Labs release Ragnarok Breaker, a browser-based roguelite auto-shooter built in the Nine Chronicles universe. The crossover event attached to it featured a 400,000 NCG tournament prize pool along with a Grade 8 Breaker Rune capable of stripping enemy buffs in Adventure, Arena and Raid content.
“Take on Fenrir, claim your loot, honor, and glory, and prove your strength,” the team said. “Good luck, Adventurers”
