Four item families move the Cabal Online economy: Slot Extenders, Upgrade Cores, Force Cores and Astral Bike cards. Everybody wants them and almost nobody knows where they really drop. This table comes straight from the Cabal Latino drop table: for each item, the place with the highest chance, what drops it and how many other places it appears in.
Table: best place for each item
Click the item name to see every place it drops, and the place to open the dungeon or map page.
The chance is per chest, boss or monster, according to the server table. 0.03% is, on average, once every 3,300 chests: high-grade Slot Extenders are genuinely rare, which is why they are worth what they are worth.

How to read the table
- Cores come from chests, not monsters. The solo DX dungeons (Panic Cave, Steamer Crazy, Catacomb Frost, Lava Hellfire) have chests with up to a 25–50% chance of a core. It is the fastest way to get them without depending on anyone: see the DX dungeons guide.
- Slot Extenders come mostly from the Labyrinth and mid-level bosses. The Low grade has its best chance in Lake in Dusk, so you can start farming it early.
- Bike cards have a minimum level (60 for Blue, 80 for RW3) and drop from dungeon chests and bosses from level 55 up: Blue already in Lake in Dusk (55) and Ruina Station (70); RW3 from Tower of the Undead B2F (105); PW5 from Forgotten Temple B2F (125); QW7 only in level 190 dungeons and the Labyrinth. The mounts guide lists every place with its level.
- If an item appears in many places with similar chances, pick the one you can repeat the most times per hour.

Before you farm
- Compare with the market: sometimes buying the item from another player is cheaper than twenty hours in a dungeon.
- Cores of the wrong grade are useless: check your gear grade in the upgrade guide.
- Keep the entry items of the dungeons where these items drop even if you are not high enough yet.
The full list, item by item, is in the item pages: over a thousand entries with every place and chance.
