Radiant Rathian — MHO Monster Research
Read available Radiant Rathian research in Monster Hunter Outlanders (MHO), including sourced ecology notes and separately labelled material candidates.
Overview
An Aesoland Flying Wyvern whose Radiantite changes enhance mobility and venom delivery.
Ecology & hunting notes
Ecology
Radiantite-corrupted Flying Wyverns unique to Aesoland. Their venom glands have developed even further, letting them launch volatile, poison-laden crystals with a flick of their tails
Hunting notes
The venom crystals fired from their tails create poison pools on the ground, which explode when struck by fire attacks. Severing their tails quickly, or staying clear of the crystals' blast radius, makes them much easier to deal with.
