D&D Illusion Spells
All 29 spells in the Illusion school of magic. Sensory deception — figments and phantoms.
What the Illusion school is built around
Illusion is the school of false perception. The spells don't create real damage or real walls — they create the appearance of damage and walls, and the targets believe them until they don't. Illusion is the cleverest school to play and the easiest to misplay; the table's tone has to support it.
How to use Illusion spells
How to use Illusion spells: lean on the bonus action and reaction casts (Minor Illusion as a cantrip, Mirror Image, Mislead). Major Image and Hallucinatory Terrain are the encounter-shaping options that require buy-in from the DM. The school works best when the table commits to playing the deception, not just rolling Investigation against it.
