The World Of Khoras - Magic

Magic is a form of energy. Like light and heat, it exhibits complex characteristics, obeys the laws of the Universe and follows certain rules. Magical energy normally passes through matter easily, but certain dense materials effectively block magic and prevent it from penetrating. In other words, spells like teleport, passwall, dimension door, clairvoyance and such can be blocked with the effective use of certain materials.

The most common material that can stop magic is common rock in all its forms. Generally speaking, stone will block magical energy with sufficient thickness. Magic will penetrate deep into the ground, but by roughly 100 to 200 meters of depth (depending on composition), it is completely blocked.

Lead is a particularly common metal that can block most forms of radiation including magical energy. With a few feet of lead, almost all magic can be blocked.

Girrall and rathani are rare types of stone on Khoras which are particularly dense and block magical energy.

Orichalcum is a heavy rock-like mineral that can store raw magical energy and because of this, wizards often use it as a form of “magical battery”. When a piece of orichalcum is filled with energy, wizards say that it is “charged”. A charged piece of orichalcum is opaque to magical energy. For this reason, charged orichalcum is more effective than any other material at blocking magic.

Because charged orichalcum is so completely effective at blocking magic, it can be shaped into thin tiles or plaques which can be incorporated in architecture. A wall covered in “charged” orichalcum tiles would effectively block all types of spells. A wizard could effectively protect a room from a teleport spell. The room would likewise be shielded from scrying, divination and most other types of spells that would need to penetrate the wall in some fashion.

The following table summarizes magic blocking metals and stones:

Material Effectiveness/Thickness 100% Shielding Achieved At Cost
Common rock Varies. Typically about 5% per meter (about 3 ft) of thickness. 100 Meters (300 ft) n/a
Lead 50% per meter of thickness 2 Meters 1 gp per kilogram.
Karrym Stone (Girall) 1% per centimeter (0.39 inch) of thickness 1 Meter 50 gp per kilogram.
Ebony Granite (Rathani) 15% per centimeter (0.39 inch) of thickness 7 Centimeters 150 gp per kilogram.
Wizard's Stone (Orichalcum) 100% at one centimeter (0.39 inch) of thickness. One centimeter 1000 gp per kilogram.
