Grand Blue Weapon Wiki: Every Cutlass, Katana & Sidearm

The Grand Blue Weapon Wiki at a Glance

The Grand Blue weapon wiki is the fastest way to find every cutlass, katana, slingshot, and sidearm in Eternal Pose's open-world pirate RPG without bouncing between fan spreadsheets. According to the official Grand Blue Roblox page, weapons have unique skills, damage values, and acquisition methods that range from a simple Weapon Shop purchase to hidden secret drops only the community has mapped out. The roster covers a basic cutlass for the first hour of play, a mid-game katana with build-defining combos, and a late-game sidearm class that can carry a PvP encounter on its own.

Players stepping into the Early Access build will quickly notice that weapon choice drives more than raw damage. Each weapon category interacts with Cursed Fruits, races, and fighting styles, so picking a grand blue cutlass is not just a starter decision, it is a build skeleton. This wiki-styled guide gives you a complete map of every weapon family in the game, the practical use case for each, and the locations that experienced players in the Eternal Pose Roblox group report as the most reliable.

The rest of the article is organized so you can jump to the section that matters for your current level. Early-game players will get the most out of the cutlass and slingshot sections, while players chasing the grand blue katana and endgame grand blue sidearms can skip ahead. All stat ranges reflect community-reported data as of the current Early Access build and may shift with future patches.

Grand Blue Weapons: Core Categories and How They Function

Before you chase any specific weapon, it helps to understand the four families that make up the full Grand Blue weapon roster. Each family has its own damage profile, stamina cost curve, and signature skill, which is why a grand blue cutlass and a grand blue katana never feel the same even when their tier is identical. Community testing shared across the Grand Blue official Discord suggests the developers tune each weapon family with a clear role in mind: one is for learning, one is for combos, one is for ranged pressure, and one is for finishing.

Weapon Family Overview

How Weapons Are Acquired in Grand Blue

Every weapon in the game falls into one of five acquisition paths, and knowing which is which saves hours of wandering. The official store page lists four broad methods — shop, forge, boss drop, and quest — but the community has confirmed a fifth: secret weapon spawns that are not marked on any in-game map. Players on the Grand Blue weapon tier list breakdown group acquisition like this:

• Weapon Shop: basic cutlass, starter slingshot, and a rotating selection of mid-tier gear that costs gold and sometimes Fruit Coins.

• Forge: crafted weapons built from ores dropped by mobs, including upgraded grand blue cutlass variants and the grand blue katana line.

• Boss drops: rare weapons that drop from world bosses on a low-percentage table, often gated by a daily lockout.

• Quest rewards: story-locked weapons handed out at major quest milestones, including unique sidearms.

• Secret locations: hidden stashes, island puzzles, and underwater caves that require exploration rather than combat.

A clean way to think about it: if a weapon is in the shop, you can plan around it. If it drops from a boss, you grind. If it sits behind a secret, you explore. The hardest weapons in the game are almost always the secret ones, and they are also the most rewarding because of the unique skills they bring.

Grand Blue Cutlass: The Starter Weapon and Its Best Variants

The grand blue cutlass is the first weapon most players swing, and it remains relevant well past the early hours because of its forgiving stamina curve and fast swing speed. According to community testing on the Eternal Pose Discord, the cutlass is widely considered the most beginner-friendly family in the entire game, yet several cutlass variants stay competitive into the late game when properly enchanted at the forge.

Cutlass Variants and Their Use Cases

Why the Cutlass Line Works for New Players

The cutlass family rewards consistent play because every swing in the combo recovers stamina at the same time it deals damage. Experienced players report that the Iron Cutlass is the first real upgrade worth chasing, since it costs very little gold but noticeably speeds up early bounties and small mob camps. The Steel Cutlass, in turn, becomes the bridge between the starter phase and the moment you can actually afford a grand blue katana without burning your entire wallet.

The cutlass also has the cleanest interaction with Cursed Fruits that buff melee damage, which is why most early race and fruit combos lean on it. A player running a melee-buff fruit and a Captain's Cutlass can comfortably clear the first island chain without touching the ranged tree at all, and that is exactly the kind of consistency the early game rewards.

If you want a step-by-step upgrade path, the grand blue forge weapons breakdown covers the ore chain required to push from the Iron Cutlass into Steel and beyond, including which enchantment rolls are worth re-rolling.

Grand Blue Katana: Mid-Game DPS and Combo Builds

The grand blue katana is where the combat system starts to feel like a real action RPG. Katanas trade the cutlass's stamina efficiency for higher burst damage and access to multi-hit skills that can shred a boss's health bar when timed right. According to the official Grand Blue store page, the katana family is a core part of the weapons roster and is highlighted alongside the cutlass and slingshot as one of the three starter archetypes.

Katana Variants Worth Knowing

Reading the Katana Combo Window

Every katana in the game has a hidden combo window, and that window is what separates a competent katana user from someone who just spam-clicks. Community guides posted on the Grand Blue Discord break the timing into three beats: opener, filler, and finisher. The opener pulls aggro, the filler chains three to four hits at standard damage, and the finisher consumes the rest of your stamina for a high-multiplier strike.

The reason players move from a cutlass to a katana is not just damage, it is the finisher's interaction with elemental fruits. Many of the strongest fruit-weapon combos in the game assume you are wielding a katana, because the finisher's multiplier scales with the element applied. A grand blue katana with a fire fruit on a burning target can push the highest single-hit damage numbers in mid-game PvE.

Players considering the move from cutlass to katana should also pay attention to stamina management. Katanas are not as forgiving as cutlasses, and the difference between a clean combo and a whiffed stamina bar is usually one or two extra swings. Practice on small mobs before you commit to a katana build in a boss attempt.

Grand Blue Slingshot: Ranged Pressure and Early-Game Kiting

The grand blue slingshot is the ranged option most new players ignore, then regret ignoring once they hit a flying enemy or a boss with a charge pattern. Slingshots are cheap, easy to upgrade, and they fill a niche that no melee weapon covers: keeping distance while still dealing steady damage. The official game description lists slingshots alongside cutlasses and katanas as part of the three core weapon archetypes a new player should learn.

Slingshot Variants and Their Range

When to Pick the Slingshot Over a Melee Weapon

The honest answer is: when the enemy design forces you to. Flying enemies, ranged bosses, and a handful of dungeon mobs with gap-closing skills all punish melee players who try to stay in their face. A grand blue slingshot lets you keep moving while landing consistent chip damage, and a charged shot from an Iron Slingshot or above can interrupt a boss's windup animation if timed right.

Players who pick the slingshot as a primary weapon tend to pair it with a Cursed Fruit that buffs ranged or elemental damage rather than melee. A common early-game combo reported by community members is a wind-element fruit plus the Hunter Slingshot, which lets you kite while stacking damage-over-time. That same player will still carry a cutlass as a backup, because the slingshot runs out of stamina fast during extended fights.

The slingshot's main weakness is its reload window, which is longer than most players expect. If you burn your full magazine on a boss and miss the timing window, you are vulnerable for two to three seconds. The Crystal Slingshot shortens that window noticeably, which is why it is the first slingshot variant most dedicated ranged players chase.

Grand Blue Sidearms: Late-Game Burst and PvP Picks

The grand blue sidearms category is where Grand Blue starts to feel like a different game. Sidearms are short-range, high-burst weapons that sit alongside your main weapon and can be swapped in for a single powerful shot or combo. They are the weapons that decide most late-game PvP encounters, and according to the official store page, they are part of the broad weapon roster that includes secret drops and rare crafts.

Sidearm Variants and Their Roles

Why Sidearms Are the Late-Game Carry

The reason sidearms scale so well into late game is their interaction with the weapon swap mechanic. A player running a grand blue katana as their main can swing two or three combo hits, swap to a grand blue sidearm, land a single high-damage shot, and swap back. That single shot often does as much damage as a full melee combo, and in PvP it is usually the difference between a win and a trade.

Sidearms are also where the most unique skills live. The Secret Sidearm in particular has a community-tracked variant with a custom skill that does not appear on any other weapon in the game, and it is one of the most-cited reasons players chase the secret weapon route over the forge route. According to the Grand Blue weapon tier list, sidearms are consistently ranked in the top half of the weapon roster for PvP, while their PvE value depends heavily on the boss design.

The cost of running a sidearm is slot pressure and stamina management. You only get one sidearm slot, and using it always opens a cooldown window where you cannot swap back to your main. Players new to sidearms tend to use them too early, which leaves them stuck in the swap animation during the worst possible moment.

How to Pick the Right Sidearm for Your Build

If you are running a melee-heavy build, the Captain's Sidearm is the safest pick because its burst window lines up with melee combo finishers. If you are running a PvP build, the Dual Pistols give you the fastest swap-to-shot timing, which is the most valuable stat in player-versus-player combat. If you can find the Secret Sidearm, it changes your entire build, because its unique skill is a full combo of its own rather than a single shot.

For a deeper look at how sidearms compare to other late-game picks, the grand blue endgame weapons guide covers the full endgame roster and the role each sidearm plays in a finished build. That page is the natural follow-up once you have a sidearm in hand and want to plan the rest of your kit.

How to Unlock Every Weapon Entry

A wiki-style guide is only useful if it answers the practical question every player has: how do I actually get this weapon? Below is the full acquisition map for the weapons covered above, broken down by source and difficulty. This section pulls from community reports on the Eternal Pose Discord and the official Grand Blue store page, and it is organized so you can scan it quickly while planning your next session.

Acquisition Map by Source

Fastest Upgrade Path for Each Family

Players who want a single, clean upgrade path should follow the same three-step pattern regardless of family: starter, shop, forge. The starter weapon teaches you the combo timing. The shop weapon is a safe gold investment that holds you until you unlock the forge. The forge weapon is the first variant that scales into mid-game content without falling off.

The moment a boss drop becomes more time-efficient than the forge path, the picture changes. A player who can reliably farm a specific boss every day is usually better off chasing the boss drop than grinding the forge, because the boss drop has a higher stat ceiling and a unique skill. The same logic applies to secret weapons, which always have the best stat ceiling in their family but cost exploration time that the forge path does not.

Building Around Your Weapon: Fruits, Races, and Fighting Styles

A weapon on its own is only half the build in Grand Blue. The other half is the Cursed Fruit that buffs your damage, the race that adds a passive, and the fighting style that defines your combo flow. According to the official store page, Cursed Fruits spawn every hour on trees and plants and can also be obtained through quests, chests, and the Fruit Trader, which means you will cycle through a lot of fruits as you progress.

Weapon Synergy Cheat Sheet

A common mistake new players make is picking a weapon first and a fruit second, when the order should usually be reversed. If you are chasing a specific elemental combo, the grand blue katana is almost always the right weapon family. If you are running a melee-buff fruit, the cutlass is a safer anchor. If you have a rare ranged fruit drop, the slingshot and sidearm become your priority weapons.

Race synergy is more subtle but matters in the long run. The race you pick at character creation adds a passive that interacts with your weapon's damage profile, and certain race-weapon pairings are notably stronger than others. The grand blue race combo breakdown covers the race side of this in more detail, including which races unlock their V2 passives and how those interact with each weapon family.

Frequently Asked Questions

What is the best weapon for beginners in Grand Blue?

The grand blue cutlass is the most beginner-friendly weapon because it has the lowest stamina cost and the cleanest combo timing, which makes it forgiving while you learn enemy attack patterns. Most players carry the Iron Cutlass until they unlock the forge, then push into the Steel Cutlass before considering a katana. The cutlass also has the best interaction with early Cursed Fruit buffs, which lets new players scale their damage without changing weapons.

How do I get the grand blue katana?

The standard path is the forge, which requires ores dropped by mid-game mobs and a small gold investment. The Cursed Katana is a stronger variant that drops from a world boss on a low-percentage table, and the Secret Katana is a hidden weapon that requires solving an island puzzle. According to the official Grand Blue store page, katana variants are part of the core weapon roster and share the same skill structure across the family.

Is the grand blue slingshot worth using in late game?

Yes, but only as a niche pick. The Crystal Slingshot and Hunter Slingshot are competitive in late-game PvE because of their anti-air and kiting value, especially against bosses with gap-closing skills. In PvP, slingshots fall off compared to sidearms because their damage-per-second is lower in close range, so most late-game PvP players swap the slingshot for a grand blue sidearm as soon as they unlock one.

What are grand blue sidearms and why are they important?

Sidearms are short-range, high-burst weapons that swap in from a dedicated slot and deal more damage per shot than any melee swing. They are the late-game PvP carry because of the weapon-swap mechanic, which lets a katana or cutlass user land a combo and then swap to a sidearm for a finishing shot. The Secret Sidearm in particular is one of the most-cited rare weapons in the game because of its unique skill, and it is tracked by the community on YouTube.

Where can I find secret weapons in Grand Blue?

Secret weapons are hidden across the game's island chain and are not marked on any in-game map. They typically require solving a small puzzle, defeating a hidden mini-boss, or finding an underwater cave. According to community reports on the Eternal Pose Discord, the most reliable way to track them is through YouTube walkthroughs, since the in-game hints are deliberately vague. Expect to spend real exploration time on each one, because secret weapons are tuned to be build-defining rather than quick pickups.
