It has azure scales of a metallic shine and a golden-colored chest.
Known as the Moon Swift Wyvern, Lucent Nargacuga has the ability to turn invisible, and perform a double tail slam like its green relative. This subspecies of Nargacuga can also extend its spikes by shaking its tail, even when not enraged. While in this mode, all of its tail attacks cause poisonous spikes to fly out in all directions.
- Lucent Nargacuga has a much harder head and chest than its two Subspecies. Only weapons with purple sharpness can successfully cut through the head and chest without bouncing off, unless the player has the skill "Mind's Eye" equipped.
- However, when enraged, both head and chest do not reflect weapons with sharpness of blue or better.
- The spikes from its tail inflict Poison.
- Lucent Nargacuga's roar has a much wider range than its other two counterparts, but still only requires standard earplugs to block.
- Lucent Nargacuga can be carved 4 times, like the Uragaan, instead of the usual 3 (although the tail can still only be carved once).
- Unlike Chameleos, Lucent Nargacuga is capable of rendering itself completely invisible, while it performs its "Strafe" or "Back Jump"-maneuver, except for the red eye trails during rage mode.
- Lucent Nargacuga can be captured, but only with shock traps (Ground is too hard to make a pitfall trap).
- Capturing Lucent Nargacuga and carving it yield the same chance at obtaining a Cloudy Moonshard.
- The Lucent Nargacuga can do a double tail slam like its predecessor, the Green Nargacuga.
- The Lucent Nargacuga can also do a double 360 Tail Swipe which throws poisonous spikes from its tail when it's spiked up.
- The fumes from Dung Bombs and Felvine Bombs are retained when Lucent Nargacuga is invisible, so hitting one with a Dung Bomb or Felvine Bomb will help players to see where it is when invisible.
- Lucent Nargacuga can be unlocked after reaching HR 40.
