100 Days At Sea Weapons Guide
Weapons determine whether you clear Sand Worm on Desert Island, survive Ghost Captain on Shipwreck Island, and DPS check Kraken in Kraken Zone. 100 Days At Sea weapon progression spans crafted melee and ranged tiers plus class starter tools like Battle Buku's Iron Sword, Sharpshooter's Scoped Rifle, and Fire Mage's Fire Staff. This guide ranks upgrade priority, boss pairings from bosses, and Pearl-efficient paths using Coins from codes for vendor parts. Pair with builds and armor for complete loadouts.
Melee Weapons
Iron Sword — Craft: 15 Iron + 5 Wood + 3 Leather from crafting. Best mid-game melee weapon. Source Iron on Shipwreck Island. Synergizes with Battle Buku (+20% melee), Swordsman (+15% attack speed), Raider (+20% damage), Hero (+10% all stats). Shark companion (+7.5% melee) or Swordfish (+10% melee) from companions.
Cutlass — Swordsman and Pirate class starters. Fast attack speed scaling — Swordsman perk amplifies cutlass DPS on Ghost Captain add phases. Upgrade path merges into Iron Sword crafting if starter insufficient for Volcano elites.
Machete — Raider class starter. Raid loot bonus pairs with melee clears on Desert and Shipwreck farming loops before Iron Sword craft completes.
Ranged Weapons
Flintlock Pistol — Craft: 10 Iron + 5 Gunpowder + 3 Wood. First ranged weapon for bosses. Mandatory before Desert Island Sand Worm unless Sharpshooter unlocked. Cowboy (+15% ranged) and Crab companion (+5% gun) amplify. Gunpowder from Shipwreck Island.
Scoped Rifle — Sharpshooter class starter. Top ranged DPS for Frost Giant weak points and Kraken surface phases. +25% ranged damage and +10% crit from Sharpshooter perk. Parrot (+7.5% gun) or Pirate Gunner (+10% gun) companions. Craft upgrades with Shipwreck Iron if not class starter.
Flintlock Pistol bridges early Desert and Shipwreck bosses until Scoped Rifle tier — do not skip gunpowder farming on Shipwreck Island.
Magic and Special Weapons
Fire Staff — Fire Mage class starter (80 Pearls). +30% fire damage and AOE attacks. Dominates Volcano Island mob packs and Lava Guardian add waves. Magma Golem companion (+10% melee) covers staff cooldown melee windows.
Tentacle Summon — Ancient Squid class starter (80 Pearls). Water ability weapon for Kraken Zone — +25% water abilities from class perk. Pair Scoped Rifle sidearm for surface burst phases.
Shield + Sword — Soldier class starter. Tank weapon set for Lava Guardian and Frost Giant — +15% defense perk reduces boss slap damage while holding aggro.
Weapon Priority by Boss
Sand Worm (Desert Island): Flintlock Pistol minimum. Sharpshooter Scoped Rifle optimal. Melee-only Iron Sword insufficient alone.
Ghost Captain (Shipwreck): Iron Sword + Flintlock Pistol hybrid. Pirate Cutlass + Pistol starter covers both.
Lava Guardian (Volcano): Fire Staff AOE or Iron Sword + Soldier tank. Iron Armor mandatory from armor.
Frost Giant (Ice): Scoped Rifle ranged weak points. Flintlock Pistol backup if crit windows tight.
Kraken (Kraken Zone): Scoped Rifle tier mandatory for co-op DPS. Ancient Squid Tentacle Summon for water phases.
Bermuda Entity (Bermuda): Hero Iron Sword + sidearm or full Sharpshooter ranged. S-tier weapon floor.
Upgrade Economy
Craft before buy: Iron Sword and Flintlock Pistol recipes cheaper than vendor equivalents when Iron stocked from Shipwreck.
Class starters skip crafts: Battle Buku Iron Sword, Sharpshooter Scoped Rifle, Fire Mage Fire Staff — factor 50–80 Pearl costs into weapon timeline on tier list.
SEAADVENTURE 50 Coins from codes: vendor weapon parts on Starter and Jungle docks when Iron short before first Shipwreck trip.
Grinder recycles failed boss attempt gear — partial Iron return before second Ghost Captain try.
