Magic Map: The main characters come across a map possessed by a demon named Grufon (as in, the minor shuhsu is stuck inside the map). The map is very accurate and offers handy shortcuts to various places. However, it also has a mind of its own, and often tries to trick the party by offering false information based on half-truths. Frequently, Grufon is threatened (usually with fire) by characters into giving the right information. Though after Yugo agrees to be his Guardian, as only highly powerful Shuhsu are allowed a Guardian, he becomes a lot more compliant.
Magic Mirror: Igor the Shushu mirror allows communication with Rushu.
Perhaps unintentionally, Evangelyne — or rather, Evangeline. Evangelyne was never sent away from her homeland and forcibly separated from her Love Interest, but the two Evas do share in common obsessively searching for said Love Interest, only to have him die in their arms soon after they are reunited by the end of the first season.
Also can be unintentional, but Yugo is Japanese for "bravery".
Nox is Latin for "night" (fitting his time-theme}, but it is also similar to "Noxa" (which means damage towards organisms), fitting with his plan on harvesting wakfu.
It's hard to say if they're still alive, but Nox uses three "warrior mummy puppets" in episode 17, each one clearly using the powers of a different class (Sacrier, Feca and Cra). Information is lacking whether they were real people before. While their official profiles on the French Wakfu page are hardly informative and consist of scarcely anything but nonsensical jokes, at least one of them heavily implies that they were indeed born as regular people. In the Wakfu game, Xelors have the ability to revive recently dead allies as mummies. Considering that many of Nox's other abilities are Xelor spells turned Up to Eleven, they were almost certainly real people that Nox kept on hand in case he needed back-up.
Evangelyne vs. Remington & Grany vs. Rubilax in Sadlygrove's body and his ghouls.
The finale of season 2 features a huge battle involving simultaneously the Sufokian Navy, Phaeris the Powerful, the Brotherhood of the Tofu, Rushu and his Shushu horde (including Anathar possessing Adama´), Goultard, and finally Qilby. It's hard to get more tangled than that.
The Merch: An in-universe example in episode 12, when everyone sells stuff with Yugo's face on it and in Real Boitar's colors.
Monster of the Week: The villain even shows up at the end of the opening credits throughout season 1, though as the season progresses and into season 2 the show begins to turn away from this format.
Mood Whiplash: So after season 1 episodes 25 and 26, which include a main character heartwrenchingly sacrificing himself and the mother of all Bittersweet Endings respectively, what was the viewer treated to? Why, a charming episode of Mini-Wakfu of course! Although originally episode 26 had a more fitting post-credits segment that shows Nox after the finale.
In season 2 episode 5, Yugo, Amalia, and Evangelyne are turned into piglets, but retain some recognizeable traits, like Eva's green eyes and freckles, or dark skin and tufts of green hair for Amalia.
Also happens with the heroes changed into Thursters in season 2 episode 13. You can still recognize them, which make the scene where Evangelyne and Sadlygrove try to touch each other that more pathetic.
And again in season 2 episode 21, when the Bellaphones turns the male members of the party into apes or monkeys.
Mr. Vice Guy: Ruel Stroud, who as an Enutrof pretty much has to be obsessed with wealth.
Ms. Fanservice: Evangelyne, especially in episode 4 or during the beginning of episode 22.
Muggle Foster Parent: Alibert, Yugo's adoptive father. Apparently, as of episode 6 of season 2, he's one for Chibi too.
My Significance Sense Is Tingling: In season 2 episode 23, when a portal opens from Rushu's World and an army of Shushus swarms the Crimson Claws, Master Goultard immediately feels it although he's in another part of the world.
Mythology Gag: The female Iop carrying a basket in episode 3 uses the same (only recoloured) animation as Goultard's mother from a previous short film made by Ankama, Goultard the Barbarian.
Near Villain Victory: At the end of season 1, Nox succeeds in draining the Sadidas' Tree of Life, wiping out their entire race, drains The Hero, Yugo, of his wakfu, and successfully becomes the first Xelor to travel backwards in time. However, the process drains all the wakfu he spent 200 years collecting and only sends him back 20 minutes.
Negated Moment of Awesome: In the first season's Gobbowl match, Sadlygrove scores a spectacular goal... only to find that he scored against his own team.
Nemean Skinning: In season 1 episode 17, Sadlygrove shears a pack of arctic dog-like beasts with one slash of his sword — without even killing them — to provide wool for his companions.
Never Trust a Trailer: Ankama seems to enjoy taking all of the most epic scenes out of an episode and throwing them into a trailer without context. It's perhaps justified, since the erratic airing schedule means that they need as much hype as possible behind each new episode.
Episode 16 was especially bad for this, coming after a several month hiatus. The trailer showed Sadlygrove screaming and surrounded by flames, wielding Rubilax with dark tendrils growing up his arms, which led to a lot of speculation about him gaining some sort of demonic power or finally having Rubilax completely take him over. In the episode itself, it was nothing but a visual cue that Sadlygrove was at his limit and that Rubilax was working ''with'' him and not against him.
The trailer for the three-episode season 1 finale was met with skepticism for this very reason. The trailer made it suspiciously obvious that Evangelyne and Sadlygrove would die together, but as it turns out, the trailer was pretty trustworthy this time around. Sadlygrove does indeed die in Eva's arms, though Eva herself is saved by the timely arrival of Ruel and his Drill Tank.
New Super Power: Yugo's wakfu training and experimentation with his portal power in episode 21 result in gaining a friggin' laser beam, which certainly made battles easier afterward.
Kriss Krass during the Bontarian Gobbowl match. His team could have very easily beaten Ruel and Co., but he didn't want of a too-easy victory, since it wouldn't give a good enough show to the crowd. So, Kriss pretends to be hurt for a part of the match, and even at the end he takes his sweet time scoring the final goal, giving Sadlygrove the opportunity to best him.
Played with in the season 1 finale. Nox drains the Sadida's Tree of Life and Yugo of their wakfu. However, he then uses that wakfu to travel back in time, undoing both of those things. Interesting in that this was what he intended from the start, and in fact the main reason he was willing to do such horrible things was his belief that they would all be undone upon his success. Ultimately averted. Nox is unable to travel back in time far enough to undo anything more than Yugo's death and the destruction of the Tree of Life, meaning that everyone else that he's killed (stated to be entire countries worth of people) stays dead. His failure to invoke this trope is one of several factors contributing to the Downer Ending.
Once again in season 2 episode 4. In hindsight, being total dicks towards Rubilax, when he still was in control of the situation, wasn't the smartest thing Shadofang and Rushu could have done. As a result, Rubilax finally decided that playing a Card-Carrying Villain sucks.
Evangelyne: Amalia and Ruel have gotten themselves turned into ghouls! Sadlygrove:Again? Ruel will end up getting a taste for it...
A much less comedic instance at the end of season 2 episode 8, when Eva watches Sadlygrove being dragged into Rushu's dimension by Anathar.
Sadlygrove says this when he sees the magic-nullifying device the second time.
Omnicidal Maniac: Rushu wants to invade the human world. Why? Because there's nothing left to destroy in the Shushu world. Destroying things for Shushus seems to be like enjoying a fine wine or a particularly nice cake for rational people. In one Creative Closing Credits, a Shushu comes upon a single untouched flower and begins excitedly contemplating exactly how he plans to destroy it, or even if he should put off destroying it so he'll have something to destroy tomorrow. Another Shushu comes along and steps on it while he's planning.
Evangelyne wears white ones (with a princess gown) in episode 4, and red ones (with a translucent dress of the same color) in episode 22. Then black fingerless long gloves are part of her standard season 2 outfit.
Our Dragons Are Different: To be specific, Grougaloragran is a shape-changing, fire-breathing old brown dragon, while Adama´ is a shape-changing, energetic, rhyming young blue-and-white dragon. He's also Yugo's brother, hatched from the same Dofus, or egg.
Our Dwarves Are All the Same: Subverted a bit with the Enutrofs. Their body isn't exactly dwarvish, and in fact they look like normal humans. But they have a love for anything glittery, adept at digging tunnels, and season 2 episode 17 mentions "the Enutrof mines" as a potential refugee camp for the Eliatrope people.
Our Vampires Are Different: Vampyro. He doesn't suck blood, but can steal your shadow and make you one of his ghouls. He isn't a true vampire, though, just a guy possessed by a demon which he has fallen in love with.
Our Zombies Are Different: They are people turned into bamboo creatures called Thursters who constantly search to quench their thirst. They've changed into these creatures from drinking bamboo milk polluted by the salt water that got into the fields. Also, they are unable to physically touch anything that isn't made out of pure bamboo, and simply phase through anything or anyone else. However, when they phase through a person, they too become Thursters. Not to mention, if you know a Pandawa song, they can't help but dance to it when you sing.
