If an enemy has it’s material listed as steel it is immune to all heat damage. I want to know if it is something in the materials.json entry or if it is a hardcoded thing.

A monster has only one material and there’s no different material for different parts.

I didn’t know that.

I guess, a monster is fire-proof when all of its material is fire-proof.

Just looked in monster.cpp in the source code on github and yep.

if( dt == damage\_heat && ( made\_of( material\_steel ) || made\_of( material\_stone ) ) ) {  
return true;

steel heat immunity is hardcoded. Well guess ill just change all the materials to one of the variety of steels then.
