One of the things I really like about Diablo III is that many of the small NPCs (non-player characters) have their own stories. Such is the case with Mayor Holus, the rotund, well dressed, guy who players first meet in Act I of Story Mode.
I suspect that Mayor Holus was placed into the game, in precisely the spot he stands in, for functional reasons. He starts out as an intentionally unlikable character. Blizzard could have left it at that, but instead, actually wrote some character development for him. It is the little things like this that make the game so interesting.
A player who goes from Paragon 1 to Paragon 100 unlocks a total of 10 Paragon Portraits. They flash by on the screen as the player is fighting a mob. This makes it hard to take a close look at them. Players who have gotten many characters to Paragon 100 – and beyond – might not care about the corresponding portraits.
Mosquito Swatter is a Feat of Strength Achievement. I happened to earn it while playing my hard core Barbarian in a Torment II Nephalem Rift during Season 4 of Diablo III. Like many things in Diablo III, the ability to earn this Achievement depends on randomness.
Season 4 of Diablo III included something new called the Season Journey. Players who complete every objective, in all of the chapters, will receive a special Portrait Frame and a Pet. I have now completed 3 out of the 4 chapters.
