Also called, "GDK"
Giant Dune Kimogila Scales (not to be confused with the regular armor components) are used for making R.I.S. Armor by a Munition Trader. The scales can be looted off the Giant Dune Kimogila (Level 70 Boss). The Giant Dune Kimogila spawns near the Kimogila Town POI on Lok (on a 10 minute respawn timer). Some say its around a 40% drop rate. The scales drop in groups of 6,7,or 8.
