The spell causes non-fire based weapons, that is, all except those related to or made with fire, to be awkward to hande. For example, obsidian weapons or fire arrows are not affected, while iron or steel ones are. This makes creatures using them to be non-proficient in their use, even if they are actually specialised in them. The creatures receive the usual non-proficiency penalties pertaining to their class.
