====== GLOWFIN RAY ======

===== Overview =====

The Glowfin Ray is a flat, cartilaginous predator native to the volcanic shallows of [[ralar_bay|Ralar Bay]] on the [[dark_side|Dark Side]] of [[the_planet_voi_700_d|VOI 700 D]]. It is named for the distinct bioluminescent streaks that run along the edges of its fins, which pulse in flowing, aurora-like patterns while hunting.

The Glowfin Ray is a top-tier predator in the geothermal ecosystem, known for ambushing prey from beneath sandy vent deposits and stunning targets with a sudden flash of light.

===== Physique and Appearance =====

  * **Size:** 1.5 to 2 meters wingspan  
  * **Weight:** 80–110 kg  
  * **Body Shape:** Flat, manta-like with broad fins and a tapered tail  
  * **Coloration:** Charcoal-black skin veined with faint obsidian-like cracks that shimmer when the body flexes  
  * **Eyes:** Reduced; relies mostly on vibration and light sensitivity  

==== Special Features: ====

  * Capable of emitting controlled pulses of bioluminescent light along fin edges, creating aurora-like waveforms to disorient prey  
  * Tail equipped with a hard, blunt spine used in ramming attacks; can emit faint geothermal heat shimmer when charged  
  * Lays dormant beneath sediment, rising with explosive force when prey is near  

===== Game Mechanics =====

  * **Armor Class (AC):** 14 (tough skin and speed)  
  * **Hit Points (HP):** 45  
  * **Speed:** 50 ft. (swimming), 10 ft. (burrow in sand)  

==== Attacks ====

  * **Bioluminescent Pulse:** Creatures within a 15 ft. cone must succeed on a DC 14 Wisdom save or be blinded until the end of their next turn.  
  * **Ram Strike:** +6 to hit, 2d8+3 bludgeoning damage  

==== Special Abilities ====

  * **Flash Ambush:** When hidden in sand, gains advantage on initiative and its first attack.  
  * **Light Tracker:** Can sense movement from any bioluminescent organism within 60 ft.  
  * **Predator Illusion:** Fin pulses can mimic the shifting patterns of smaller prey schools, luring targets closer.  

===== Behavior =====

  * **Diet:** Carnivore; feeds on Deepfish, crustaceans, and smaller rays  
  * **Social Structure:** Solitary hunter  
  * **Activity Pattern:** Nocturnal ambusher, active during thermal surges  

==== Survival Strategies ====

  * Camouflages beneath geothermal sediment to avoid detection  
  * Uses aurora-like fin light pulses to confuse, blind, or lure bioluminescent prey  
  * Delivers ramming strikes with its heated spine when cornered  

===== Reproduction and Lifecycle =====

==== Reproductive Traits ====

  * **Mating Season:** Unknown; believed to be solitary except for mating  
  * **Birth:** Ovoviviparous; gives live birth to 1–3 offspring per cycle  

==== Lifespan and Growth ====

  * **Total Lifespan:** Estimated 20+ years  
  * **Juvenile Phase:** Young rays remain hidden in shallow tidepools until strong enough to hunt  

===== Tactical Advice for Dungeon Masters =====

Glowfin Rays are a threat-level encounter in geothermal zones, perfect for stealth-based or horror-themed aquatic adventures.

  * **Vent Guardian:** A ray might defend a sulfur pool suspected of hiding ancient tech or forbidden relics.  
  * **Unexpected Predator:** The graceful aurora glow of its fins might first appear beautiful — then suddenly turn deadly.
