Magorian (3.5e Equipment)
From D&D Wiki
A mineral attuned perfectly to arcane magic. Must be blended with mithril or adamite to be used as armor or weapons without losing its proporties. It can be used as a conduit for magic or an impediment to magic. In its rarest purest form it can even absorb magic derectly from a caster. Highly anti-magic societies have used pure magorian to this effect as often as they can.
Armor made from magorian has no arcane spell faliure chance as it channels the magic through the metal but all proporties of mithril or adamite are lost in this process. A weapon made of magorian forces any arcane caster struck to make a DC 20+the level of the spell cast concentration check or lose his next spell. Weapons of this type can also channel arcane touch spells. Armor of Magorian alloy blocks up to 10 spell levels a day. Pure magorian is the bane of mages. The magorian absorbs magic from a caster at the rate of one spell per round starting with the lowest. This affects any helpless (unable to cast any spells) casters within 20ft of the rock. This ability can be suppressed if cold iron touches the rock. This drain is permenant but the spells can be restored to the afflicted by means of touching the rock and making a DC 15 will save. None but the original owner can take these spells. The power within the rock can be used to create magic items as the caster could have if the afflicted had all the craft item feats possible for his level. This ability can only be used if all the spells have been drained from the target. A DC 20 will save by a user allows him to utilize this ability. The rock loses XP and requires components as usual for item creation. Magorian can hold 100 spell levels per pound.
