Reversible
Range: 60 yds. Sorcery Level 2
Duration: Special Casting Time: 1
Area of Effect: 10 sq. ft./level Saving Throw: None
The knock spell opens stuck, barred, locked, held, or wizard-locked doors. It opens secret doors, as well as locked or trick-opening boxes or chests. It also loosens welds, shackles, or chains. If used to open a wizard-locked door, the spell does not remove the former spell, but simply suspends its functioning for one turn. In all other cases, it permanently opens locks or welds--although the former could be closed and locked again later. It does not raise barred gates or similar impediments (such as a portcullis), nor does it affect ropes, vines, and the like. Note that the effect is limited by the area; a 3rd-level wizard can cast a knock spell on a door of 30 square feet or less (for example, a standard 4-ft. x 7-ft. door). Each spell can undo up to two means of preventing egress through a portal. Thus if a door is locked, barred, and held, or triple locked, opening it requires two knock spells. In all cases, the location of the door or item must be known--the spell cannot be used against a wall in hopes of discovering a secret door.
The reverse spell, lock, closes and locks a door or similar closure, provided there is a physical mechanism. It does not create a weld, but it locks physically operated locking mechanisms, set bars, and so on, up to two functions. It cannot affect a portcullis.

Range: 10 yds. Priest Level 2
Duration: 1 turn Casting time: 1 rd.
Area of Effect: 1 creature or object Saving Throw: Neg.
A know alignment spell enables the priest to exactly read the aura of a creature or an aligned object (unaligned objects reveal nothing). The caster must remain stationary and concentrate on the subject for a full round. If the creature rolls a successful saving throw vs. spell, the caster learns nothing about that particular creature from the casting. Certain magical devices negate the power of the know alignment spell.
The reverse, undetectable alignment, conceals the alignment of an object or creature for 24 hours.
