Ice Queen / Great Mage / Dragon Goddess
These are tied to current top sword conversations, so their materials can matter even when the drop itself is rare.

Farm priorities
Best boss farms to check first
Cosmic Being / The World
Sea 2 bosses are high-effort and patch-sensitive. Farm them when their title, style, or material path matches your build.
Sea beasts and summon bosses
Use luck/drop boosts only after the spawn or summon cost is ready. Some source notes mention no pity on specific sea-beast drops.
Structured table
Sailor Piece boss drops snapshot
Rates and requirements can change after updates. The table below summarizes public boss wiki notes and keeps uncertain items phrased as reported source data.
| Boss / route | Entry or spawn | Notable drops | Why farm it |
|---|---|---|---|
| Escanor / Boss Rush | Boss Rush entry with Rush Key | Escanor weapon, Sun Armor, The One title | Late-game weapon/title chase; source notes list difficulty-based rates. |
| Aizen | Mid-to-late boss route | Mirage Pendant, Illusion Prism, Reiatsu Core, Hogyoku Fragment | Accessory and material farming before higher routes. |
| Saber / Qin Shi / Ichigo | Summon bosses with Boss Keys, cash, and gems | Saber sword, Jade Tablet, Imperial Seal, Soul Fragment, Spiritual Core | Good planning target because failed summons still cost resources. |
| Shadow / Cid Dungeon | Dungeon waves | Umbral Capsule, Void Seed, Shadow-route materials | Useful when dungeon farming also supports your sword path. |
| Great Mage | Sea 2 event-style summon route | Ancient Mage title, Great Mage sword materials, Ancient Fragments | Strong sword target and possible Sea 2 unlock overlap. |
| Kraken / Sea Serpent | Sea creature spawns tied to bounty and distance from islands | Dragon Goddess materials, Dragon Queen title materials, reroll-style rewards | High-value Sea 2 farm; plan around spawn rules and team damage. |
Sea 2 bosses
What changes in Sea 2
Public wiki notes describe Sea 2 bosses and sea creatures as much larger HP checks than Sea 1 routes. Treat these farms as coordinated sessions, not casual drive-by kills.
- Check whether the boss is spawn-based, summon-based, or dungeon-only.
- Confirm whether the route has pity before spending rare keys.
- Use codes, luck boosts, and drop boosts only after the farm is ready.
Map pieces
Bosses also matter for Sea 2 unlock
Community Sea 2 notes currently map the 7 Map Pieces to boss pools such as Saber/Yuji, Gojo/Sukuna, Jinwoo/Qin Shi, Aizen/Rimuru, Ichigo routes, and Gilgamesh or Strongest in History. Use this as a routing checklist, not a guaranteed drop order.

Boss drop checklist
Write down the target
Know whether you want a weapon, title, material, map piece, or accessory before you start.
Check the entry cost
Summon bosses can cost keys, cash, gems, or event items, so failed planning wastes more than time.
Stack boosts deliberately
Drop and luck boosts should line up with confirmed spawns, not with travel or waiting time.
Track source changes
When a boss is new or event-tied, expect drop notes to move quickly after patches.
