Can Minor Illusion be used to replicate non-physical attacks?

Recently as a player my party fought against a creature that could paralyze you if you looked at it. Since my rogue has now seen it, would it be possible to replicate this using Minor Illusion by creating a image of the creature, and would it work the same way or be less effective? Could this also be used to replicate the attack the creature used that could kill if you failed the saving throw?

Can I Minor Illusion a 5ft box around myself to write notes when I know I am being scryed on?

My party is being scryed on by an enemy. We are all low level and don’t have access to second level spells yet. Can I get out paper and quill, cast minor illusion around myself as a 5ft cube of hollow stone, and write down sensitive information. Then pass the folded up paper to a party member and cast the illusion around them so they can read it? My theory is that because the scrying sensor is always 10ft away from the target they would just see a block of stone.

From Scrying:

On a failed save, the spell creates an invisible sensor within 10 feet of the target. You can see and hear through the sensor as if you were there. The sensor moves with the target, remaining within 10 feet of it for the duration.

Limitations on the Conjurer’s Minor Conjuration ability

There are some clearly defined limitations already on the Wizard School of Conjuration’s Minor Conjuration feature, however…

Does normal “wear and tear” count as damage? (e.g. I’m in a fight without a weapon, and create, say, a dagger or club. Will it hold up through the fight?). How about a bottle of ink? Does dipping my pen into it and writing a quick note “damage” the ink?

Is it one piece? ( e.g., can I use it to make a temporary replacement for a set of Thieves’ Tools (which is ‘an item’ on the equipment list) or is it limited to one contiguous item, such as a skillet, or a coil of rope?)

Can a Minor Illusion block light?

The Minor Illusion spell say:

If you create an image of an object – such as a chair, muddy footprints, or a small chest – it must be no larger than a 5-foot cube. The image can’t create sound, light, smell, or any other sensory effect. Physical interaction with the object reveals it to be an illusion, because things can pass through it.

Can the illusory object block light? And if not, what would a creature see?

For example, could a vampire mage use the Minor Illusion cantrip to protect himself from the light of a sun blade? Could a wizard create an illusory box around a torch to “turn off the lights”?

How do NPC’s of a faction know one of the party members is a member of their faction? (careful: minor spoilers in question)

I’m currently running LMoP for 4 players. One of them has already joined the Lords’ Alliance, and I expect another to join the Emerald Enclave in the near future.

I’m planning to run SKT next, and have already started reading the book. The factions are mentioned quite often, and usually in a way that if one is a member of the faction they can get free lodgings/special items/a special quest.

I wonder though… how would they know they are part of their faction?

  • Would they be wearing a symbol on their clothes (such as a pin)?
  • Would they have to explicitly state to the NPC that they are a part of this faction?
  • Or would the NPCs simply be already informed about the new member and his/her appearance?

Any other possibilities?

Can I use Minor Illusion to create a wall, hide behind it, and attack with advantage?

Minor Illusion allows the creation of a 5-foot illusory object: can I hide behind this object (wall/crate/anything) and gain advantage vs. creatures who can’t see past the illusion?

If so, given that examining the illusion requires an action, am I guaranteed to have advantage at least until their turn arrives?

Can the object created by Minor Illusion be carried or worn?

Looking at the RAW for Minor Illusion (PHB, page 260) and other questions, I recognize that Minor Illusion is very limited in its ability to move on its own or change its appearance. However, I’m wondering if the illusory object can be carried or worn as demonstrated in two examples:

  1. I want to convince a visiting noble that I’m the ruler of this small town, so before I meet him in the city center, I cast Minor Illusion to create a crown on my head. Assuming he doesn’t investigate (or fails) does it continue to sit naturally upon my head through normal movements?

  2. I’ve just stolen a historical battleaxe and the guard have been alerted to its absence. Can I choose someone who is rapidly walking away and cast an illusory version of the battleaxe strapped to his back as a diversion? Does this usage work until the illusion is investigated or interacted with (as normal.)

Conjure (Minor) Elemental into a Hallow spell, does it just fail?

Hallow states “Celestials, Elementals, fey, Fiends, and Undead can’t enter the area…” but it doesn’t say what would happen if someone tried to summon some into the area. Would the spell fail? Would the elementals appear but then be forced to leave?

Would the ruling be the same for both Conjure Minor Elementals and Conjure Elemental? The latter uses a source of the element (e.g. a fire, what if the fire is in the Hallow area?) while the former just makes some minor elementals appear from an unspecified source.

Can Minor Illusion/Silent Image be used to make it look like you’re about to cast other spells, to waste enemy Counterspells or Dispels?

Can the “Minor Illusion” cantrip or “Silent Image” spell be used to emulate the casting of other spells?

Thus hopefully tricking another spell caster into wasting a 3rd lvl or higher spell slot to cast “Counterspell” or “Dispel”?

If you have played any spellcaster capable of casting Counterspell you know every time someone announces what spell they are casting like a well placed “Fireball” you or your foe jumps right up screaming “Counterspell”. So far I have seen no one describe the visual appearance of the casting of a spell any spell other than a DM before/after announcing the spellĀ“s name and level.

I’m specifically thinking of using the cantrip to emulate the casting of a different spell, not the effect. Just enough of a deception attempt to look like a spell is starting to complete casting, to make another spellcaster react.

Intended Examples:

  • A ball of fire to emulate Fireball or a similar imagery like a bright glow at the tip of the PCs pointing finger to emulate the casting of said spell or even “Delayed Fireblast Fireball”.

  • Covering yourself in illusory flames to emulate “Investiture of Flame”.

  • Making your hand glow brightly to emulate “Sunbeam”.

  • A levitating disk of light to emulate “Portal”

I expect that in most of these cases an opposed or contested ability check would be required from one or both spell casters.

At a 60ft distance (maximum range for Counterspell) you would not hear the verbal incantations nor see the somatic movements very clearly if at all. So, the best indication would be any visible change like a glowing hand or finger. “Minor Illusion” only has a Vocal and a Material (a bit of fleece). “Fireball” (for example) has a Vocal (that would not be easy to heard), the Material (tiny ball of sulfur or bat guano) would be in your closed hand/fist (unable to be seen), and the Somatic component could be made mockingly or completely improvised. So, by making your finger glow, you could fool another spellcaster into thinking you are casting “Fireball”.
