Creeping Shadow

This spell causes the casters shadow to elongate, stretching away from their body at a rate of 20 feet per round. It can elongate a maximum distance of 60 feet. The shadow moves as an ordinary shadow, along floors and up walls. The caster may maneuver in any manner feasible to place the shadow where they desire. A caster might position the shadow over a high window in a tower in order to spy on the tower's occupants. The shadow makes no sound and is largely undetectable in all but the brightest surroundings. While the spell lasts, the caster can see, hear, and speak through the shadow. The shadow cannot physically touch, pick up, or attack creatures or objects. It can be struck only by spells, magical weapons of +1 or better, or other special attacks (such as a dragon's breath). The shadow has the same Armor Class as the caster and 10 Hit points. Hit points lost by the shadow are suffered by the caster. To cast the spell, the caster must be in dim light or darkness.

At higher levels. For every spell slot above 1st, the shadow can extend 30 extra feet. At 4th level, the shadow can become 3 dimensional and can physically interact with the enviorment, but still cannot attack.
