If the object suddenly appears, or a light is suddenly dowsed, a creature would be likely to investigate the event more closely, especially given that their senses are actually contesting the magic whether they fully realize it or not.įor example, could a vampire mage use the Minor Illusion cantrip to I also expect there will be clues presented in such a scenario that warrant allowing creatures to make an investigation check. So I would expect that someone fooled by the spell would be tricked by the magic into thinking the light was blocked and would "see" the environment in whatever reduced lighting conditions this caused. Creatures who haven't figured out that it is an illusion should see the image as though it were the intended object, with all of its requisite visual properties. Implying that the image appears solid otherwise. "If a creature discerns the illusion for what it is, the illusion becomes faint to the creature." So we have to posit that the image can block your view of things behind it, including light sources, if you're fooled. Certainly an object that light passes through when it shouldn't normally, such as a stone wall, would raise suspicion and give the illusion away. If the image can't block light, then it would be transparent, or at least translucent, which would severely limit the utility to the point of near uselessness. Could a wizard create an illusory box around a torch to "turn off the lights"? I would ultimately say that it's up to you to decide where to draw the line, but that the rules state this is nothing but an illusion and doesn't have an effect on any properties of the world around it.Ĭan the illusory object block light? And if not, what would a creature see?. I feel like a wizard casting Minor Illusion to block the light of a campfire from an enemy patrol is an engaging and creative use of the spell.

I feel like it'd be really interesting to be able to feel the warmth of a torch or fire behind by an illusory wall. There are some great opportunities here for roleplay. The effects of those things impacting a player would still apply (and perhaps give them a hint as to the object's illusory quality). Things can pass through the illusory objects even if a creature or player can't register it passing through with their eyeballs. This illusory object impedes nothing and is only an illusory trick of the eye, but this is where the concept of magic comes in. When the book references this, it's not just talking about a physical object like a rock. "Physical interaction with the image reveals it to be an illusion, because things can pass through it."
