- Badass Decay: Hordriss. When first introduced, he's a dangerous character with an agenda of his own; not as powerful as either Big Bad, but definitely a force to be reckoned with. By the last couple of series, he routinely falls for every simple trick that Lord Fear or Lissard use on him and is only still on deck because of dungeoneers showing up in the nick of time to save him.
- Growing the Beard: It's widely accepted among fans that despite its insane difficulty in comparison to what came later, Series 3 was by far the best of the show's run.
- Ho Yay: Between Treguard and Pickle.
- Nightmare Fuel: The life force meter. It took the form of a knight's helmeted head for the first 5 seasons. As the Dungeoneer gradually lost health, pieces of the knight's helmet broke off and flew away. Okay, not so bad. But then when the helmet was completely gone, the skin of the knight's head began peeling away to reveal a skull underneath, as the face goes through a series of suitably shocked and horrified expressions until it no longer has lips to emote with. And after that, the skull itself cracked and fell apart, the remaining chunk of it flying towards the camera to leave just the eyes which then rolled out of the screen one by one. BONG! "Ooh, nasty."
- Painful Rhyme: Frequently, in the Previously On sections. Also, Treguard's closing verse in series 6 required him to rhyme 'foul' with 'hour' every week. Lampshaded in one recap:
They perished, all: though what a pity
It does help rhyme this awful ditty.
- Spiritual Licensee: Though an official American adaptation never got off the ground (see the Trivia tab), two shows did kinda follow in its' footsteps: Nick Arcade, which mixed the game-playing action of Starcade with a bonus round like this show; and Masters Of The Maze, where there was more CGI and physical props, less chroma key, and more of an educational bent.
- That One Level: The Corridor of Blades claimed more dungeoneers than any other trap in the show.
- The Causeways count, too. Sure, you would need to know the combination to get past, but then the thing would start falling apart to place false pressure upon you.
- The Scrappy:
- Gundrada the Swordmistress from series 4. Quite a fun character and helpful to the teams but her ridiculous (and very annoying) voice earned her plenty of hate from the viewers.
- Snapper-Jack from Series 8, mostly due to the poor execution of the character, which makes him look less like a man with a dragon-like creature in place of his arm, and more like a really bad ventriloquist act.
- Seasonal Rot: Series 4-7 are generally regarded as a step down from, at the very least, Series 3. Series 8 is much more divisive, as some fans appreciated the return to the format of Series 3, though many feel that it was poorly executed and suffered from decisions such as allowing the last two teams to skip straight from Level 1 to Level 3.
- What an Idiot: A team was once told to not wake up the dragon and to use a spell first, and an advisor then insisted they wake the dragon up first.
