Illusion Art Feat

You master the arts of illusion, mastering a special art to create them through a unique method. You gain the following benefits:

Prerequisite: 4th level

• Mind Tricks. You learn the Minor Illusion cantrip and cast it without a material component, using a spellcasting ability modifier of our choice. When you form a weapon with Minor Illusion, you can use it as if it were a real weapon for the duration. You can only form a weapon you have proficiency with. On a hit, it does psychic damage instead of its normal damage type.
• You gain the Illusion Steps special bonus action (below).

Illusion Steps - Active Ability (Bonus Action, Supernatural)

• You can cast Mirror Image as a bonus action without expending a spell slot. When cast in this way, it conjures a number of duplicates equal to your proficiency bonus. When you cast this ability or as a bonus action while it is active, you can move one or more of the duplicates out of your space, moving them up to your movement speed. A duplicate outside of your space looks just like you and mimics your action, but if you attack or interact with anything while it is not in your space, it is revealed as an illusion until it returns to your space.
• If you start your turn with one or more duplicates not in your space, you can either recall them to your space or swap positions with one (destroying the duplicate in the process).
• Once you use this feature, you cannot use it again until you complete a long rest.

Mystic Path Feat Save DC:

• Any time a mystic path feat requires an ability score modifier for spell attacks or saving throws, use Constitution as the modifier. The DC is calculated as 8 + your Constitution modifier + your proficiency bonus.
• If your class grants you a spellcasting feature, you can use that ability modifier for calculating spell attack rolls and the DC instead of Constitution.
