True Image

You create the image of an object, a creature, or some other visible phenomenon that is no larger than a 250-foot cube. The image appears at a spot that you can see within range and lasts for the duration. It seems completely real, including sounds, smells, and temperature appropriate to the thing depicted. You can create sufficient heat or cold to cause damage, a sound loud enough to deal thunder damage or deafen a creature, or a smell that might sicken a creature (like a troglodyte's stench). When an attack roll is made by anything created by the illusion, the ability modifier for the attack and damage rolls is the spell caster's arcana modifier + whatever other effects the creatures suffer in the illusion (if any). When one or more creatures is in the range of an effect like previously stated, they must make a X saving throw, X being up to the DM based on what the player has created/attacking with. On a failed saving throw against the spell caster's spell save DC, the creature(s) take up to 15d10+Intelligence score damage in whichever damage type chosen by the caster. This damage must be split evenly if the said magical effect or a multiattack by a creature created by the illusion was used. On a successful saving throw, the creature(s) take half 15d10+Intelligence score damage in whichever variety it is given on X saving throws or attacks If a condition is forced under these effects, a creature may attempt to break out/free themselves with either a check relating to the illusions' shape or magical effects. Only one condition effect can be afflicted onto the target creature(s) each turn i.e. this spell cannot inflict the Blindness and Poisoned effect on the same turn. Any attack, saving throw, or effect can be repeated within reason (not on the same turn if said effect had already taken place) to whatever the illusion is attempting to create (i.e. any multi-attacks, D.O.T. saving throws, lingering effects, magical effects of a replicated spell or ability {with exception to specific class abilities, spells the caster's class cannot cast themselves through natural level up progression, and the wish spell}). All magical effects creatures are under and all lingering magical effects resulted from the spell vanish whenever the spell ends. 

As long as you are within range of the illusion, you can use your action to cause the image to move to any other spot within range. As the image changes location, you can alter its appearance so that its movements appear natural for the image. For example, if you create an image of a creature and move it, you can alter the image so that it appears to be walking. Similarly, you can cause the illusion to make different sounds at different times, even making it carry on a conversation, for example.

Physical interaction with the image reveals it to be an illusion, because things can pass through it. A creature that uses its action to examine the image can determine that it is an illusion with a successful Intelligence (Investigation) check against your spell save DC. If a creature discerns the illusion for what it is, the creature can see through the image, and its other sensory qualities become faint to the creature.

This is a spin off of the spell Major Image from Dungeons and Dragons Fifth Edition, edited for a character in a specific campaign for the purpose of being awesome. Make sure this is chill with your DM before whipping out this spell. Also, recommend for Illusion mages ;)

At Higher Levels. When you cast this spell using a spell slot of 12th level: the spell lasts until dispelled and does not require concentration.

P.S.: (If a situation came to where you choose to not take an action again with the spell, it shall repeat its last given command until completing. If the spell is then not given a task by the next turn, the magic centers around the AOE around the user and will wait to do anything until given another command. It has no additional effect.
