@JeremyECrawford I know you must get this all the time, but I can't find a real definitive answer on the subject. If I used Mirage Arcane to transform a lake of water into a lake of lava, would someone interacting with that lava take lava though it was an illusion? #dnd5e

The mirage arcane spell gives you tremendous latitude in how you make the affected terrain look and feel. The altered terrain can even hurt someone. You could drown in the spell’s illusory lake, for example, or fall off an illusory cliff. #DnD https://t.co/DaSN2OmxvI
