Deep Dungeon & Cubera Mine

The Deep Dungeon is a five-floor version of the old Dungeon, filled with elemental copies of its monsters (their names start with Deep D). Only characters of level 770 or higher can enter. Use the Deep Dungeon entrance gate in Lorencia at (177, 31), or pick Deep Dungeon in the warp command window.

Every floor drops jewels, normal and Excellent weapons, Excellent Holyangel mastery armor and elemental items. Floor 3 adds normal and Excellent rings, and floors 4 and 5 add necklaces as well.

Cubera was the first mine ever dug in MU. Miners say the monsters came after a group of Kundun worshippers held a ritual at a nearby altar. A few at first, then too many to handle, so the mine was shut and left empty. When gems and minerals ran short, the people asked MU's warriors to clear it out.

• Level 850 or higher. Walk in through the Entrance to Cubera Mines in Devias at (158, 57), or use the move command for 50,000 Zen.
• The map has two parts: the Mining Area and the Old Mines, where the monsters are stronger and nastier.
• Five elemental field gates (Fire, Water, Earth, Wind, Dark) all lead to (209, 69).
• In the safe zone you can mine minerals with Pandora's pickax.
• Main drops: Excellent Blueye armor (including the Blue Eye Rune Wizard set). The mines also drop the Awakening Soul Crystal used for mastery gear.

Entry stayed at level 850, but Webzen has lowered the monsters and the level you need to hunt without a penalty several times:
