All Known Forbidden Spells in Witch Hat Atelier, Explained

In Kamome Shirahama’s Witch Hat Atelier, magic is not an innate genetic gift, but a physical craft executed by drawing precise geometric ink circles called magic crests. Because anyone can cast a spell with the right tools, the magic system fundamentally functions as an analogue for technology and weaponization, which we have understood all too well due to the ongoing airing of Season 1 on Netflix and Crunchyroll.

It treats forbidden magic as more than a simple “dark arts” category. The ban itself comes from the “Day of the Pact,” when the Pointed Hat witches outlawed magic that is drawn on or affects the human body, with memory erasure as the major exception, while also banning spells that dangerously warp the environment. However, the show’s main antagonist, the Brimmed Caps, are the only ones to use these forbidden spells and usher in chaos.

1 The Scalewolf Curse Crosses a Line No Witch Should Cross

The Scalewolf Curse is a forbidden spell that permanently transforms a body, and its first confirmed use is in Chapter 23, when Sasaran casts it on Euini during the second pentagram test. The spell fuses Euini with his mirror cloak and turns him into a scalewolf, making the violation brutally physical and irreversible in its immediate effects. That is exactly why witch society forbids it because it rewrites a living person’s body against their will.

2 The Anti-Scalewolf Curse Challenges the Rules of Magic

The Anti Scalewolf Curse appears in Chapter 29, where Iguin uses it as leverage after first demonstrating that it can return Euini to human form. The spell is described as nullifying the effects of the Scalewolf Curse. In Chapter 28, Coco, Agott, and Tetia invent the Inverted Scalewolf Curse, which is explicitly not forbidden and only heals Euini’s mind, not his body. The anti-curse functions like a moral mirror to the original curse: if one spell can forcibly strip away personhood, the other becomes a desperate attempt to restore it.

3 Petrification Is the Reason Coco’s Journey Began

Petrification is the spell that opens the entire story in Chapter 1, when Coco copies it from the magic picture book and nearly turns her house and mother to stone before Qifrey intervenes. It’s a forbidden spell that turns everything nearby, living or not, into a rock-like, unknown material. In ethical terms, petrification is forbidden because it is indiscriminate. It does not merely target an enemy; it erases the distinction between person and surroundings.

4 The Illusory Labyrinth Weaponizes Fear and Confusion

The Illusory Labyrinth appears in Chapter 6 and is used by the Brimmed Hat Group to trap Qifrey’s apprentices inside an underground maze that loops space itself, so escape becomes impossible. The spell’s forbidden status makes sense on two levels: it is an extreme environmental distortion, and it is also a tool of imprisonment. It weaponizes architecture, turning space into a prison without bars.

5 Twin Bottle’s Spell Reveals a Dangerous Ethical Gray Area

Twin Bottle’s Spell debuts in Chapter 12 and is described as a forbidden spell that can teleport fluids from one place to another. The healing witches of old used it to transport medicines over long distances before it was outlawed on the “Day of the Pact.” Later, Iguin weaponizes that same spell by covertly using it on Coco’s ink, implying the transfer of a blood-infused substance into her possession without her knowledge. The spell could provide care, but in the wrong hands, it becomes contamination through distance.

Taken together, these five spells show why forbidden magic is one of the strongest parts of Witch Hat Atelier’s worldbuilding. The series aired its first episode on April 6, 2026. Season 1 will have 13 episodes, and the finale episode is scheduled for June 22.
