Curse of Pirates marks are modular upgrade items inserted directly into your ship's ability slots to transform baseline attacks with elemental effects, summoned allies, and damage modifiers. Rather than serving as passive raw stats, marks alter how your active and passive skills behave during a voyage, turning standard broadsides into elemental chain reactions.
This guide details everything officially confirmed about obtaining, managing, and upgrading marks in Curse of Pirates (developed by Funky Parrot and published by HeroCraft PC).
What Marks Do in Curse of Pirates
In Curse of Pirates, your ship's build depends heavily on the interaction between chosen skills and the marks assigned to them. According to official developer updates and playtest notes, marks feature distinct rarities and power tiers.
When equipped into ability slots:
- They add secondary mechanics to weapons. As player reviews observe, unmodified weapons fire basic attacks, while socketing marks introduces effects such as poisonous puddles, ignite triggers, tentacle summons, and curses.
- They allow cross-element builds. Combining marks with specific captain abilities lets you tailor attacks around elemental affinities, including Fire (Astrid Flameheart), Venom (Lord Darkbown), Madness/Curse (Zar'kul), and Wind (Zephy).
- Ship hull versions dictate your capacity. The layout and number of available ability slots directly depend on the specific hull version of the vessel you take to sea.
How to Get Marks
Marks can be discovered during active voyages and unlocked permanently through metaprogression.
In-Run Exploration: Treasure Chests
During a run, the map generates two distinct types of resource exploration nodes:
- Shipwrecks: Visiting these boosts your ship's base stats for the run.
- Treasure Chests: Opening these nodes yields marks to equip into your active abilities.
Opening chests requires navigating the archipelago and dealing with surrounding enemy swarms. The game's meta-currency—Treasures, converted from collected gold, wood, and stone—can also be spent in the Hub to unlock access to these chests and shipwrecks.
Metaprogression and the Shipping Journal
Developer patch notes confirm that metaprogression focuses on unlocking new abilities, modifiers, and marks rather than simple raw stat boosts. Once unlocked, newly discovered marks are cataloged in your Shipping Journal, an in-game logbook that tracks your discovered items, marks, abilities, and enemy entries.
How to Equip and Merge Marks
Equipping and fusing marks is tied directly to in-game achievements and ability loadouts:
- Equipping Marks: Access your ship's ability menu during a run and insert your acquired marks into compatible active or passive skill slots. Doing this unlocks the Branded for success Steam achievement.
- Merging Marks: The game features an upgrade mechanic allowing you to merge marks together to reach higher tiers of power. Upgrading a mark all the way to Tier 5 unlocks The Sacred Mark Steam achievement.
Confirmed Mark Elements and Synergies
Developer updates have expanded the variety of marks available to complement different crew members:
| Element / Theme | Associated Crew or Effect | Gameplay Interactions |
|---|---|---|
| Wind | Zephy (Interdimensional Parrot) | Introduced in Update 1.0 to support bouncing tornadoes, whirlwinds, and dash cooldown scaling. |
| Fire | Astrid Flameheart | Synergizes with burning tar, explosions, and fire damage milestones. |
| Poison / Toxic | Lord Darkbown | Inflicts expanding clouds of rotting green venom on enemy swarms. |
| Madness / Curse | Zar'kul The Mad | Spreads plague-like curse debuffs across marked enemy packs. |
| Summoning / Deep Sea | Leviathan Ship Hull | Empowers allied summons, tentacles, and creature-based attacks. |
Frequently Asked Questions
Where can I check which marks I have discovered?
You can review all discovered and unlocked marks in your Shipping Journal from the game menus.
How do I get more marks during an active run?
Look for Treasure Chest points of interest across the map. Unlike Shipwrecks (which grant stat boosts), Treasure Chests are the dedicated resource nodes that provide marks.
What is the maximum documented level for merging marks?
