You cloak yourself in sharp spikes of darkness. Although they are weightless and do nothing to impede you, your foes soon discover that they are not so lucky.

You cloak yourself in shadow and shift the light that would reveal you into the Plane of Shadow.

While this mystery is in effect, you can attempt Stealth even while being observed, just as if you had cover or concealment for the purpose of this determination.

Darkness coalesces about your body, forming a shadow-shape of armor and another that looks like a shield. Although they are as weightless as the air, you know they'll protect you as well as if they were made of steel.

Steel shadows grants you a +3 armor bonus and a +3 shield deflection bonus to AC, but without weight, armor check penalty, arcane spell failure chance, or speed reduction. The effect is not a force effect, and attacks from incorporeal creatures ignore it.
