Stone of Inethril

From World of Kralis

These blood red stone balls very in size from 10" in diameter to over 24' in diameter and are used to contain magic that are created from blood sacrifices. All the stones are a deep blood red. When they are being used they pulsate from deep red to a bright red. They are often used to harness and focus magical energies, most are used to power larger items such as the Gates of Kralis and the mighty and ancient Kithar, as well as the casting of the [Barrier], a spell created by Rayche Blackstone.

Many mages and wizards use them in magical experiments as well as powering portals in other planes of existence.

Creating a Stone of Inethril is a long a difficult process that requires a mage to get a hold of a perfectly chiseled stone of a specific diameter, which is based on the amount of blood or fatigue that the stone is meant to contain:

6'-6"	150	80	4000 sp
7'-0"	175	90	5000 sp
7'-6"	200	100	7500 sp
8'-0"	250	125	10,000 sp

9'-6"	400	200	17,500 sp
10'-0"	450	250	20,000 sp
10'-6"	500	300	22,500 sp
11'-0"	550	350	25,000 sp
11'-6"	600	400	27,500 sp
12'-0"	650	450	30,000 sp
per every 6" beyond 12'-0"	100	50	5,000 sp

Once the stone has been procured, the mage must then sacrifice the appropriate amount of either Fatigue Points or Health Points as required by what he is attempting to do. Immediately (1 to 2 hours) following this the mage must then cast Gird Object and Permanence.
