Fusion Caster

Summary
The Fusion Caster allows you to create weapons at the cost of materials you gathered from dungeons and Tix. This is a very important service that you can access in the basement and attic in order to create better weapons to progress, although there is a chance that a boss can straight-up drop a weapon instead of just materials. Additionally, for weapons from insanity dungeons, they can be boosted a decent amount using fifteen Insanity Pulses.

Downstairs
There are three categories of fusion items which are the dungeon items, insanity items and class items.

Trivia
