I find myself crafting a whole set of fire resist gear in every playthrough and almost never using it. The only time I actually use it is when I plan to start large fires or have to snatch a fire-based artifact from its resting place.
Are there plans for enemies who use or cause fire to be in the game so that this gear can be more useful? Perhaps a boomer level after the point where their bile makes you glow that vomits explosion and fire-inducing nitroglycerine and also explodes in a big ball of fire when killed? Boomers are frequent enough that I think it would be a valid point of concern for a player in the late game when boomers reach an evolution level like this.
Also the gas bloaters can be used as a fire catalyst. I haven’t played the experimental version yet as I’m having too much fun with my current characters so I don’t know if a thing like this is in or not, but I’m thinking that their gass could ignite if it comes in contact with electricity, fire, or experiences gunfire. It would add another layer for players to think about when dealing with bloated zeds.
