Fishing

 is an activity of the character to gain Materials by standing next to Water and tossing a line into the water by left clicking while holding a Fishing Pole.

Catching Fish
While the line is in the water, and the character has "Bait" in their inventory, the line will eventually get a "tug" (slight movement of the float and a sound effect) indicating that the character has caught something.

Left clicking a second time after casting will retract the line. Performing any action other than movements will retract the line. Grappling, dashing, flying, swimming and other movements are all allowed, but only to a distance of monster spawning.

Rewards from Fishing
Many things can be gained from fishing, including a boss summoning. Some things will be useless.
