Overview
A Radiantite-corrupted Flying Wyvern with exceptionally hot breath.
Ecology & hunting notes
Ecology
Radiantite-corrupted Flying Wyverns unique to Aesoland. They expel a substance that solidifies upon contact with air, then detonate it with fireballs, mercilessly punishing any intruders that enter their territory
Hunting notes
When frenzied, they unleash a barrage of powerful flame breath attacks, leaving solidified deposits on the ground that explode when struck by fire. Interrupting their powerful breath attacks as quickly as possible to prevent more deposits from forming is key to a successful hunt.
