What faith does in Graveyard Keeper 2
Three uses, one figure and a set of gaps. Everything below is taken from the sources listed at the bottom of this page; where a number is missing it is left missing rather than filled in.
Research at the study table
Studying an ingredient permanently reveals its red, green and blue runes for the alchemy laboratory. Studying always costs science, and some ingredients also cost faith — so faith gates part of the list rather than all of it.
Raising a zombie
Resurrection consumes a corpse, zombie juice and faith. Faith is the one input of the three you cannot get from the morgue, and it is the only place in the supplied material where a faith price is written down.
Buying Perks and Inspirations
Perks grant upgrades or raise skill levels, and the small Inspiration quests are what unlock the option to buy them with Faith. The review describing this also warns that later levels get expensive.
