Should dragonfire be added as an item? It's one of the few things that can hurt important story elements later, and there are classes and skills that mention it specifically. This chapter has the first mention of dragon fire: "the first thing he would have done would be to blow pure Dragonfire at any intruder in the vague hope it would work"
Possibly also a spell or ability, similar to Ryoka? If this route, do we want to mention these type of references in chapter summaries?
