Fishing poles enable the player to catch fish, which can transform your pet into a monster.
The type of fish fed to your pet determines its form and whether it is transformed into a monster. Among other things a fishing pole can catch are rings, gems, and weapons. Many artifacts are much more likely to be found through fishing than randomly in the dungeon. Fishing spots are present in town, and some dungeon levels. Fishing spots are marked by a group of fireflies swarming above a body of water or body of lava on some dungeon levels.
Fishing poles cost 200 gold to buy and have a find rarity of 850.
