Giant Crystals are used to upgrade C-grade melee mercenaries. They are dropped primarily by monsters in Mohenjodaro's Shadow, the Shadow Dungeon of Mohenjodaro Graveyard. They can also be bought from the Market for a fixed price of 80,000 gold.

Each mercenary can be upgraded twice using Giant Crystals. The first upgrade can be performed at level 20 and requires 50 Giant Crystals.
