Transfiguration

Biodata

Scope

Magical principles

• Will and form — In Dumbledore's theory, Transfiguration releases a subject from its fixed form into a “changing state.” The caster needs a clear, strong will to give that state a new form; imagination alone is insufficient 989.
• Self-perception — Anton identifies a person's understanding of who they are as a key factor in Human Transfiguration 401.
• Memory and animal instinct — Anton concludes that animal memories drawn from the Fantastic Beast Collective Consciousness can displace a transformed wizard's own memories, reshaping the body and affecting judgment. Stronger instincts can increase physical ability while reducing control 489 490.
• Body and bloodline — Anton later observes that bodies and bloodlines influence magic during transformation, alongside the caster's memories, emotions, will, and thoughts 759.
• Effects on surroundings — Dumbledore argues that a transformed form can conflict with its environment: the surroundings push it back toward its original state, while a sufficiently powerful transformation can also change the surroundings 989.

Notable applications

Human and creature forms

• Anton develops the Color-Changing Windbird from an imitation Charm into a form he considers part of his own being 123.
• Anton's modified Animagus work allows several Cabin members to transform and turns the rabbit Angnagara into a human girl 359.
• The Antlered Great White Bear transformation preserves a wizard's access to certain powers in bear form, but its animal instincts can create an urge to attack 401 472.
• Anton proposes a controllable, non-contagious Werewolf Animagus transformation; Neville later teaches and develops combat uses for it 530 759.

Animated objects

• McGonagall makes snow-white cats that investigate a house and intercept an attacking vine. Anton contrasts their independent, lifelike behavior with his Moving Figurines, whose movements require his control 344.
• Anton animates a brass pen holder while preserving its character as an object. His Killing Curse does not affect it because it has no soul 453.
• The Guardian Knight Charm can create armored figures, though Ron's newly made knights do not respond when he orders them to charge. Anton explains that a creation's actions and endurance require sustained support from the caster's mind 926.

Study and qualifications

• Grindelwald directs Anton to Dumbledore's papers in Transfiguration Today for advanced Human and Cross-Species Transfiguration. McGonagall later recommends the journal for Anton's Animagus research 208 524.
• Transfiguration is an O.W.L. subject. An Auror candidate must later earn an Outstanding in the Ministry's Transfiguration examination; Healer training requires a Transfiguration N.E.W.T. certificate graded at least Exceeds Expectations 329 1120.
