Very Rare Requires Attunement
A fanciful twisting rune that confuses the eye with ever shifting patterns of colors.
Passive Effect. When marked on an item, an attuned wearer can cast ever more convincing illusions. Creatures have disadvantage on their first Intelligence (Investigation) check to determine if a spell you cast is an illusion (the first check it makes against that spell).
Active Effect. You can cause one illusion you’ve made to become real. This effects a 10 foot by 10 foot cube of the illusion if it is larger than that. This can’t create an object worth more than 100 gp, lasts 1 hour, and can’t create a creature of a CR greater than 5 (when attempting to, it may create a weakened version of that creature, or simply fail). If the illusion directly causes damage (from falling on a creature, or otherwise being harmful) it can deal a maximum of 8d8 damage (potentially split across multiple creatures). This limit doesn’t apply to creatures created through it. Once activated, it can’t be activated again until the next dawn.
