S+ Tier
Plague Halberd
Overall the best melee weapon in the game. Its special ability is a high damage AoE and heals. Works in all scenarios - bosses, camps, boarding fights. Halberd has a good moveset with long range.
Dragon's Breath
The best ranged weapon in the game. Special attack does massive AoE damage on top of the already high damage of Blunderbuss, which is the best ranged weapon type.
S Tier
Reliable Blunderbuss
Another Blunderbuss which deals big damage. The knockback is at worst useful and at best extremely valuable versus certain enemies such as Plague Warriors.
Arboris Saber
Similar weapon effect to the Plague Halberd but smaller and doesn't heal. Scales with Strength so can use it alongside the Halberd if you wish.
Soul Eater
Best greatsword in the game. Greatsword has a strong weapon moveset with wide cleaves and a long range poke. Ability has a long cooldown but it works well as a secondary/support weapon.
Plague Pistol
Pistols in general are not great, but the weapon effect is very strong as a secondary for healing. Also fires 2 times per reload which isn't mentioned in the tool tip.
A Tier
Executioner
A stacking up to 30% crit chance buff which lasts 1 minute is very strong. Great weapon for clearing camps
Rapier of Devastation
Great single target weapon. At full 8 stacks does huge damage with heavy attack. Best versus bosses, but Blunderbuss is simply better in these cases.
Rapier of a Thousand Cuts
Has lower damage per hit than Rapier of Devastation, but bleed effect is very strong in single target.
Reliable Musket
Best Musket in the game with a faster reload and great accuracy compared to the others. While having lower damage than a Blunderbuss, this is still worth using while hitting enemies from range or hunting animals.
Blunderbuss
Even a regular Blunderbuss is still very strong and pumps out damage.
B Tier
Razor
Simple effect of increased Crit Chance. Nothing special but still solid, especially early-mid game.
Sturdy Halberd
Same as Razor, another strong early-mid weapon.
Stalwart Greatsword
Ability is unremarkable but Greatswords have great attack patterns so still decent.
Dueling Greatsword
Unreliable ability but saved by a strong attack pattern. If you are a god, this weapon gets a lot better.
C Tier
Cutlass
Applies a stacking damage buff for Pistols. Pistols are generally not great and the best one, the Plague Pistol, is mostly used for its utility.
Dueling Saber
Gives extra damage when Perfect Blocking. This buff can be hard to stack up but more importantly does not last very long and is removed when you take damage. Using Razor is just better.
Sturdy Rapier
+1 Posture point is barely better than a green weapon
Sturdy Saber
Same as Sturdy Rapier
Rapier/Saber/Greatsword/Halberd
Standard green weapons with no special effects. Use these to discover your preferred playstyle and attack patterns!
Buccaneer's Friend
Slightly more accurate than the Reliable Musket but its slower reload makes it a worse option.
Reliable Pistol
Firing 3 times before reload chews through ammo but makes it pump out better damage.
Drake's Double-Barreled Pistol
Very similar to the Reliable Pistol but less... reliable. Fires twice before needing to reload (though does reload faster), unfortunately sometimes fires twice in very quick succession hurting its consistency.
All Maces
Every Mace special effect is underwhelming. The weapon attack pattern is also nothing special.
D Tier
Infantry Musket
Poor accuracy for a musket. Has a melee attack that scales with Agility. Intended to be a good all round weapon, but is simply all round bad. Worse than green musket.
Pistol/Musket
Just poor overall weapons. Severely lacking, especially compared to Blunderbuss.
Worn-Out Pistol/Broken Blade
These are your starter weapons. Replace them when you can!
