Skull and Bones, Ubisoft's live-service pirate naval game, continues to receive seasonal updates in Year 2 (Faction Wars), introducing new content, gameplay modes, quality-of-life improvements, and bug fixes. Updates are structured around seasons, with mid-season patches addressing community feedback. Below is a summary of the most recent patch notes and updates from 2025, based on official sources. The game is currently in Year 2 Season 2 (Oaths of War), launched on July 15, 2025, with a maintenance patch on July 29, 2025, and a developer letter released on August 5, 2025.

Earlier 2025 updates built on Year 1 foundations, but the focus shifted to Year 2 with larger-scale additions like massive bosses (e.g., a Kraken encounter) and expanded PvP. Patches often include warehouse expansions, AI improvements, and exploit fixes, with mid-season updates responding directly to player input.
Year 2 updates have introduced new ship-related blueprints and features, emphasizing large-scale naval warfare. While core weapons (e.g., cannons, torpedoes) remain craftable via blueprints obtained through vendors, farming, or bosses, new content focuses on expansions like large ships and customization. Blueprints are typically acquired by tracking items in the in-game codex, purchasing from specific outposts/dens, or crafting after looting materials. Here's a breakdown of notable new additions and related blueprints from 2025:
| Blueprint/Item | Description | Acquisition Method | Update Introduced |
|---|---|---|---|
| Frigate (Large Ship) | Iconic Golden Age of Sail vessel for large-scale battles; supports heavier armaments and crew. Enhances PvP and faction wars with superior durability. | Crafted via new blueprint from seasonal events or Megafort challenges; requires high-level materials. | Y2S2: Oaths of War (July 2025) |
| Battle Junk (Ship Variant) | Added in earlier Year 1 Season 3 updates but expanded in 2025; focuses on combat utility with new cosmetic sets. | Blueprints via boss drops, codex tracking, or vendor purchases at outposts. | Y1S3 (Expanded in 2025 tools/support) |
| Long Gun Upgrades | Enhanced versions for precision damage; blueprint locations include specific dens. | Buy from vendors or craft after looting; updated in Y2 for balance. | Ongoing, refined in Y2S1.1 (May 2025) |
| Legend of Lestari (Cosmetic/Weapon Set) | New ship and weapon cosmetic blueprints tied to seasonal themes. | Seasonal rewards or crafting. | Y2S2 (July 2025) |
Many blueprints remain consistent from launch (e.g., all weapons like culverins or mortars are craftable via vendor-specific purchases), but 2025 updates add over 50 new items, including cosmetics and ship variants for Season 3+ onward. For full locations, track in the codex or refer to community tools. New content often ties to Megaforts or PvP modes like Death Tides, where looting yields blueprint materials.
