Cliché Storm: Part of the charm of any Blizzard game albeit more darker than most.Big-Lipped Alligator Moment: For some odd reason in Diablo's 16th floor chamber, there's a random Black Knight Mook amongst the much more powerful Blood Knight and Hell Mage enemies.

Better Off Sold: The copious amounts of low-quality weapons and armor you come across are good for gold.

Excusable because in actuality, the body you're fighting him in is that of a helpless child. Doesn't help that there is an easy way to lure him out without waking his mooks. His only ranged attack is a simple blockable instant hit explosion but can be prevented by going melee, he's fairly susceptible to common magic, and he has pretty low armor class.

Alt-itis: The series was born for this.
