Cubing

Using cubes at Fredrick

In the Free Market, open Fredrick (NPC 9030000), choose one of the cube items shown in the menu, then select a non-cash equipment item. The script removes one selected cube and calls the server cube routine for that equipment. Its dialogue mentions a meso cost, but the active transaction removes the cube item and does not deduct mesos.

• The NPC filters its equipment list through getEquipNoCash(), so cash equipment is not offered by this path.
• Use the in-game item tooltip and Fredrick menu to verify that a cube is accepted before spending it.
• The menu performs one cube action at a time. This page can run a local batch for practice; it does not automate or send actions to the game.

Cube types and progression

The community guide describes Miracle Cube, Super Miracle Cube, Black Cube and Supreme Cube as a progression. Fredrick 9030000 currently lists four item IDs: #2583000, #2583001, #2583007 and #2583005, but the active script does not confirm which name belongs to each ID. Use the in-game item tooltip to verify the name before spending a real cube.

• Miracle Cube: the guide describes a three-line ceiling and a chance to lose extra lines.
• Super Miracle Cube: the guide describes a four-line ceiling and a chance to lose a fifth line.
• Black Cube: the guide describes up to five lines without line degradation.
• Supreme Cube: the guide describes the strongest potential values and a harder-to-obtain item.
• Rainbow Cube: the guide describes rerolling one selected line, with a 25% item-destruction risk that a Golden Protection Scroll can prevent. Its item ID and active use route are not confirmed by Fredrick 9030000.

Custom potential options

The server loads ItemOption data and classifies custom option IDs into stat families. The active custom families include Total Damage, Boss Damage, Drop Rate, EXP Rate, Meso Rate, Overpower, Item Drop Power, Ignore Enemy Defense, All Stats and individual base stats. Exact eligible options and values depend on the item option data and equipment requirements.

• Equip stores five potential fields; the client and server resolve each option against the equipment.
• The local practice tool uses illustrative sample lines only. It does not reproduce the server option weights, tier chances, or exact values.
• Community-guide statements about holding Y for extra lines, Rainbow Cube risk and cube sources are reference notes, not verified rates from the active Fredrick script.

Where to find cubes

The community guide lists Super Miracle Cubes among notable drops from early and mid-game bosses, Black Cubes from Vellum, and Rainbow Cubes from the Spirit of Harmony. Drop tables can change, and the server NPC script does not define reward sources; check the current Drops Database and each boss guide before farming for a specific cube.
