FIDS is an acronym for the 4 resources found in Dungeon of the Endless:
Science, which is used to research new modules, upgrade existing ones, as well as to reset character abilities in combat.
Most of these can be produced by major modules, and all of them are vital to your survival in the dungeon. For example, having more dust leads to a higher energy capacity, which increases the crystal's health, while industry allows the construction of major modules, which increase FIDS production.
There are several different ways to procure FIDS in the game:
- Major Modules - The amount of FIDS acquired from these is directly correlated to the amount of the appropriate modules you have, and the wit of the heroe(s) you assign to said modules
- Exploration - Upon opening doors, you may be rewarded with some Food, Industry, Dust, or Science in slightly varying amounts.
- Mob Kills - Killing mobs may earn the player dust, industry or food.
- NPCs - Trading items to merchants will give the player more of the resource the merchant deals in.
