Shadowstuff

At-will, swift, ranged, concentration; you create an object out of shadowstuff. While you concentrate, it is real, it has mass, and it interacts with the physical world. The object can be any macroscopic form that fits within a medium-sized space (large at rank 2). If you manifest an inanimate object, it has the normal properties of that object (e.g. a sword, a brick wall, etc).

At rank 2, you can manifest any creature of your level -4 that fits in the space, which can act as your minion. The creature can only use physical actions — it can't use magic. Otherwise the creature has the same abilities and statistics as normal, including Hit Points — at 0, it dissipates.

All such conjurations look normal, except they are substantially darker in tone and drained of most color.
