Sigil
(Conjuration/Summoning)

Range:  0
Components:  S, M
Duration:  Permanent
Casting Time:  1
Area of Effect:  Object touched
Saving Throw:  None

The wizard may inscribe or write his personal sigil, emblem, or seal over any non-magical item. The sigil will prevent the opening of any door, chest, or lock until dispelled, and any person touching the item inscribed with the sigil (other than the wizard) will receive 1d4 points of damage. If a knock is used to open the item inscribed, the item will open normally, but the damage is still inflicted. The material component of this spell is a key, which is consumed in the casting.
