Hookbat

The Hookbat is an enemy found that spawns at night after accepting the Durasilk quest from the Adventurer. They always spawn in groups of 4 when the quest has been accepted and will drop a Durasilk Sheaf upon death as long as the player has no other Durasilk Sheaf in their inventory. They will fly around the player trying to hit them and will randomly dash towards the player in order to inflict damage.

Hookbats are one of a few enemies that can be detected with an Lifeform Analyzer.
