- Anvilicious: The game's Central Theme of about how Love and Friendship will always prevail is about as subtle as a sledge hammer to the head.
- Arc Fatigue: A common complaint with many of the worlds (especially during the second arc) is that they can go on and on for what may seem like an eternity.
- Special mention to Azteca, widely considered one of the longest and most tedious worlds in the game. Between its enemies that now almost always start the fight with a hard-hitting spell, the obnoxious amount of bosses, and the constant backtracking to older areas, it has an infamous reputation amongst players.
- Ascended Meme: Around the time of the Zafaria update, KingsIsle released a video about an employee traveling to Africa to record animal sounds. It ended with a joke where he returns to find the developers considering doing a world called "Penguinonia" instead. Players briefly latched onto the name of the world, and several years later the Penguin revolutionaries in Polaris got "Viva la Penguinonia!" as their battle cry.
- Complete Monster: Queen Morganthe Malory, a student of Ravenwood Academy, got banished into the void after she tried to study black magic in order to defeat her teacher. When a character discovers her plans, she then attempts to kill this person and then sell out her brother to her teacher to get into her teacher's good graces. After escaping the void, Morganthe seeks the power from the planet Celestia by ravaging the entire world in a war. It was also revealed that she tricked a king of a realm by wearing a cursed crown, and when said king turns against Morganthe, she attempts to poison him. In the realm of Azteca, she summons the spirits of the dead, which she uses to capture and torture the inhabitants so that they could make her a weapon. Morganthe then summons a meteor to destroy Azteca. Before the final battle, she mocks her opponent about the destruction of Azteca, and when defeated, attempts to erase the former's memory. A cruel, sadistic and selfish sorceress with a massive god complex, Morganthe eventually goes on to attempt to destroy the world to recreate it in her own image.
- Evil Is Sexy: Morganthe is a truly irredeemable monster, but many fans would be lying if they said she wasn't attractive.
- Funny Moments: Ozzy is practically Wizard101's Deadpool, with his constant ramblings being both hilarious and Leaning on the Fourth Wall.
- Genius Bonus: Any fan of Arthurian Legend will figure out that King Artorius and the Pendragon are one and the same, or at least have a connection, long before The Reveal, considering that King Arthur's (Artorius' inspiration) last name is Pendragon.
- Moral Event Horizon: Morganthe destroying Azteca using the comet Xibalba was the moment she cemented her status as a truly irredeemable villain.
- Narm Charm: The ending of the Castle Darkmoor dungeon is so over dramatic that it would qualify as Narm in literally an other scenario, but the fact that it has Malistaire finally reunite with his deceased wife, Sylvia and end a plot line that's been around since the beginning of the game on a note that is both heartwarming and sad makes it extremely satisfying to watch.
- Nightmare Fuel: The way Morganthe dies isn't the best way to go. She gets so overwhelmed with power that the ground beneath her collapses, causing her to fall into the Void between the Worlds. It should be noted, however, that Malistaire eventually landed Darkmoor after being sucked into the Void at Xibalba, so Morganthe might have landed somewhere else.
- The cutscene at the end of Empyrea's first act is kind of terrifying, mostly due to how cold Raven's reveal of her plan to end the Spiral is. Hearing the game's kindly, ever-present narrator as a villain is jarring, especially for long-time players. The ominous music definitely doesn't help, either.
- The Scrappy: You'll be hard pressed to find anyone who actually likes Nolan Stormgate.
- Sidetracked By The Golden Saucer: The game has many, ranging from gardening, pet training, fishing, etc. but none hold as much of a sway on the player base than PvP, with many investing in the game solely to engage in combat with fellow wizards.
- That One Boss: Belloq is one of the most infamous bosses in the game. He's a cheating boss, but unlike other cheating bosses up to this point not fulfilling his cheat (which is to hit him every round) will allow him to cast a 0 pip Ra which has a gigantic amount of damage by this point in the game. Players will really need to team up here because he's insufferable if you're attempting to solo.
- Tier-Induced Scrappy: In PvP, Ice is a high-tier example. They have a robust statline and frequently have some of the best class exclusive equipment and their stuns and shields can also be very annoying to deal with.
- When Death got the spell Bad Juju, which does about the same amount of damage as Sacrifice or Dark Pact to yourself in exchange for putting a -90% Weakness on your opponent, they became this for a while until the spell was partially nerfed.
- What Do You Mean, It's for Kids?: While the game itself is targeted towards Kids, it also deals with a lot of heavy-handed subjects such as death, grieving a lost loved one, slavery and oppression, and insanity.
