Hide in Shadows

A Thief can try to disappear into shadows or any other type of concealment - bushes, curtains, crannies, etc. A thief can hide this way only when no one is looking at him; he remains hidden only as long as he remains virtually motionless. (The thief can make small, slow, careful movements: draw a weapon, uncork a potion, etc.) A thief can never become hidden while a guard is watching him, no matter what his dice roll is - his position is obvious to the guard. However, trying to hide from a creature that is locked in battle with another is possible, as the enemy's attention is fixed elsewhere. The DM rolls the dice and keeps the result secret, but the thief always thinks he is hidden.

Hiding in shadows cannot be done in total darkness, since the talent lies in fooling the eye as much as in finding real concealment (camouflage, as it were). However, hidden characters are equally concealed to those with or without Infravision. Spells, magical items, and special abilities that reveal invisible objects can reveal the location of a hidden thief.
