Edge of Mirrors (Tanares)

You create a number of small magic mirrors, equal to your spellcasting ability modifier, about half a foot square each, distributing them anywhere within the spell’s range. The mirrors are invisible, but can be seen through spells such as detect magic, or by creatures that have true sight, or the like. You, and any creature you allow, are able to see the mirrors. When a creature that can see the mirrors is adjacent to one of them, it will be able to see what is reflected on all other mirrors. In addition, spellcasters who can see the mirrors, and are adjacent to any of them, can cast their spells as if they were positioned at the location of one of the other mirrors. The spell cast in this way cannot have the range of touch. Creatures that are in spaces adjacent to the space occupied by one of the mirrors can sense their presence with a successful DC 18 Wisdom (Perception) check The mirrors have 5 hp, AC 13.
