Chamber Ward

Abjuration (Ward)
Tier: 3
Components: Verbal, Somatic, Material
Casting Time: 8 hours
Range: 0 ft
Area: One single room, up to 2500 square feet
Duration: 1 year/level (D)
Saving Throw: None.
The glamer melts away, and the intruder stands before you, exposed and vulnerable.

This potent ward strips away deceptions and keeps out dangerous creatures.

Any illusion or enchantment effect entering the area of the spell is attacked, as if you had attempted to dispel it (using the tier of this spell). Any illusion or enchantment effects cast within the area are counterspelled in the same way. Apportation effects fail automatically if they try to move anything into or out of the warded area.

Additionally, elementals, undead, and all but the most powerful daemons are barred from entering (and even these are likely to suffer greatly)

This ward is uniquely tied to your magical power. The ward reduces your spell point maximum by 3 as long as it exists. You can only have one chamber ward at a time, and the spell ends if you die. You can ignore all the spellcasting limitations of the ward, and your caster level rises by one within its area.

Material Component
The eye of a dragon, burned as the spell is cast. Silver salts mixed with moonflower petals to form the boundary.
