OSRS Winter Summit 2026 Roadmap: the big picture

Old School RuneScape’s Winter Summit 2026 laid out a fairly packed year, with seasonal competitive modes, a new beginner-friendly boss, a full League, a summer-long balance pass, and a long-awaited Grandmaster quest finale. This recap follows the announced timeline and focuses on what each update actually adds, what rewards to expect, and what you can do now to be ready when the content lands.

The roadmap is presented in chronological order: Deadman Annihilation in late January, a new cow boss expected in February (pending a poll), League 6: Demonic Packs in April, Summer Sweep Up rebalancing through summer, and the Grandmaster quest Blood Moon Rises later in summer as the capstone to the Morytania storyline. Community events, seasonal updates, and future raid plans were also teased for later in the year.

January 30: Deadman Annihilation (seasonal mode)

Deadman Annihilation begins on January 30, runs for three weeks until February 20, and culminates in a finale on February 21. Unlike the separate Deadman Allstars event (creator-focused), this is a public seasonal mode that anyone can join.

How the point system works

This season is framed more like Leagues in terms of progression: you earn points by completing a wide spread of activities rather than only focusing on PvP. The summit callouts included:

• Leveling milestones
• Collection log unlocks
• Clue scroll completions
• Diary completions
• Boss kills

Those points convert into cosmetic rewards in the main game after the season ends. That matters for two groups of players in particular:

• Iron accounts, because these cosmetics are otherwise difficult or impossible to obtain through trading
• Main accounts, because some cosmetic rewards can become valuable if they are tradable and in demand

Breaches and efficient point chasing

Breaches were highlighted as a potentially strong point source. If you’re approaching Deadman primarily for rewards rather than PvP, treat breaches as the first activity to test early: if they’re dense with objectives (kills, loot milestones, task chaining), they’ll likely beat slower, single-track grinds.

Also plan around the one-hour PvP protection window you receive when starting out and when moving into new brackets. That hour is the difference between a smooth setup (quests, early levels, basic gear) and getting reset by early hunters.

Deadman Annihilation rewards (cosmetics)

The summit showcased three main reward categories for this season, purchasable with Deadman points. Exact pricing was shown in the reveal, and the key takeaway is that these are cosmetic unlocks intended to carry over to the main game.

• Annihilation Teleport Scroll: a home teleport animation unlock
• Annihilation Weapon Scroll: cosmetic toggles for select items (shown for Toxic Staff of the Dead, Bow of Faerdhinen, and Crystal Armour)
• Annihilation Blueprints: a themed cosmetic set (presented as a POH-style theme)

One open question from the reveal: whether the weapon scroll is a single unlock covering all supported items, or if you’ll need multiple scrolls (for the staff, the bow, and each armour piece). If the scroll is item-specific, expect the point grind to scale up quickly for completionists.

It was also suggested you may be able to spend points on previous Deadman rewards via Nigel, which would make this season useful even if you don’t care about the new cosmetics.

Finale format and timing

The finale begins at 18:00 UTC on February 21. Worlds open one hour earlier, and players are teleported to Damon’s Crater. The structure is:

• Players split into two teams and receive team capes to prevent friendly fire
• After enough eliminations, the event transitions into a free-for-all

No real-world prizes were mentioned for winners, which reinforces that this iteration is aimed more at seasonal participation and reward chasing than high-stakes competition.

February (expected): The cow boss and “The Ides of Milk” poll

Before League 6, the roadmap calls out a new low-level boss expected in February, assuming it passes a poll: The Ides of Milk, a free-to-play quest that unlocks a repeatable cow boss encounter.

OSRS has introduced “teaching” bosses before, but this one is positioned as even earlier: something you can attempt within your first few hours. That makes it important not just as a novelty, but as a bridge between early combat and the game’s broader PvM ladder.

A “hard mode” version was also teased, with some form of gating so brand-new players don’t stumble into it. The summit commentary implied it may be genuinely challenging compared to what people expect from a cow-themed boss.

Boss rewards overview

The reward list is split between free-to-play and members-only items.

Free-to-play rewards

• Cowbell Amulet: teleports to the Lumbridge East cow pen; charged with air runes; also speeds up milking by one tick
• Rump Steak: heals 10 HP
• Bull Bones: a larger-bone drop analogous to other early boss bone upgrades

Members-only rewards

• Cow Slippers: cosmetic footwear
• Bottomless Milk Bucket: a storage-style utility item themed after bottomless buckets
• Mooetta: an off-hand shield-slot item with modest accuracy and a +1 Strength bonus (presented as steel defender-level stats)
• Pet: boss pet drop
• Cowbat achievements: a themed achievement set tied to the encounter

April: League 6 “Demonic Packs” (8-week league)

League 6: Demonic Packs is scheduled for April and will run for eight weeks. Like prior leagues, everyone starts fresh as an Iron-style character with boosted progression, but the structure has a few key design points worth planning around.

Core rules and progression

• Fresh start: you begin as a new Iron account within the league
• Multipliers: accelerated experience and improved drop rates
• Packs (relic-like power): the league’s power system is framed as “demonic packs,” replacing or evolving prior mastery systems
• Region-locked: you start in one region, then unlock additional regions by completing tasks and earning points
• Not all regions unlockable: you must choose a path based on the content you want to focus on

The starting region was kept secret, with one explicit confirmation: it will not be Misthalin. The tutorial takes place in a new version of Yama’s lair, with the Sage “locked up” as the narrative hook.

Echo bosses and practice value

The reveal mentioned bringing back echo bosses from a previous league. Echo variants are popular because they often let you jump directly to the fight, which is valuable practice for mechanics-heavy encounters. If your long-term goal is to improve at challenging PvM in the main game, this is one of the most practical reasons to play the league even if you don’t care about ranks.

Sailing was explicitly excluded from this league due to its recency and ongoing iteration. The stated policy going forward: newly released skills won’t appear in alternate modes for roughly 12 months after release.

League 6 rewards (cosmetics and overrides)

The reward pool is heavily cosmetic, with several high-visibility overrides:

• Demonic Packs outfit
• Demonic Packs banner
• Home teleport animation
• Yama’s Throne: a demonic throne override
• Thralls override: imp-style thralls replacing the default look
• Weapon ornament kits: Trident of the Seas, Trident of the Swamp, Iban’s Staff, Soulreaper Axe
• Oath Plate Slayer Helm: two variants (standard and radiant)
• Demon butler override for player-owned house
• Demon skin color

Summer: “Summer Sweep Up” rebalancing returns

After prior years’ broad balancing initiatives, Summer Sweep Up returns in 2026 as a seasonal umbrella for systemic tweaks. While the summit didn’t list every targeted change, it framed this as a continuation of the philosophy behind recent adjustments: healthier drop tables, cleaner progression, and better long-term balance.

What this initiative tends to affect

Based on what Summer Sweep Up-style projects have included previously, expect changes to land across multiple categories rather than a single piece of content:

• Combat and NPC defenses
• Drop table tuning
• Gear rebalancing and niche strengthening
• Quality-of-life improvements
• Potentially more polling on individual adjustments

If you’re planning long grinds, keep an eye on these windows: they can shift the value of certain methods, items, and bosses, sometimes dramatically, especially when drop tables or defensive profiles are adjusted.

Summer: Grandmaster quest finale “Blood Moon Rises” (Morytania conclusion)

Blood Moon Rises is positioned as a Grandmaster quest that concludes a storyline that began in 2005. Requirements shown in the reveal include Sins of the Father and A Night at the Theatre, with additional skill requirements to be confirmed closer to release. A high combat level was recommended.

Major rewards (spoiler-light summary)

The summit went into reward specifics. If you prefer to stay fully unspoiled, treat this section as a high-level overview of what the rewards are designed to do.

1) Blisterwood flail upgrade

A new untradeable flail upgrade is planned as a best-in-slot option for vampire slaying, created during the quest. It requires 50 Attack and is intended to improve the experience of vampire-related combat (including Slayer tasks and other vampire hunting goals).

A second untradeable two-handed weapon reward is designed around a consistent special attack:

• 50% special attack cost
• On a successful hit, it always deals 70% of its maximum damage
• If the target is below that threshold, the attack instead rolls at 70% of its maximum accuracy, emphasizing reliability as a finisher

The design intent is clear: this is primarily a vampire-focused tool, with situational use elsewhere when you need a predictable execute-style hit against targets that become harder to hit late in a fight.

Vampirium: a new destination beyond Gielinor

During the quest, players will travel beyond Gielinor to Vampirium, described as the vampires’ ancestral homeland. The reveal highlighted new creatures and flora to establish the atmosphere and stakes of the finale.

Bloodwood trees and Bloodwood sap

A new skilling component was previewed: Bloodwood trees that provide Bloodwood sap. This is targeted at mid-to-high 70s Woodcutting and is positioned more as a valuable resource activity than a pure XP method. Two approaches were described:

• AFK method for steady gains
• More interactive method for improved rates and engagement

Community events and later-year teases

The roadmap also included recurring items like quality-of-life and seasonal events, plus community-facing beats:

• Deadman Allstars (creator event): teams drafted May 31, starts June 6, finale June 20 in Chicago
• RuneFest: planned for October 3–4 at the NEC Birmingham (UK)
• Autumn bingo community events: listed as a seasonal community highlight
• Next winter raids: a raid plan teased for the “Fractured Archive”
