A "brown letter k" represents a kobold in the ASCII-based roguelike game NetHack. Here's all the monsters you can find in that game. As I got "bold" from "kobold," get other words from the ends of these monsters' names, and extract the number indicated in parentheses:
The last one is a little tricky, because several demons in NetHack are represented by purple amersands. But only one of them ends with a string that I can interpret as "explosive."
The extracted letters spell the answer, LEMURE, which is another NetHack monster. You could even get another word out of the end of it, if you consider "re" a word... and why wouldn't you? But don't treat "re" as the answer. It's LEMURE.
