Spell Stone

Enchantment
A spell stone stores a spell until someone (even a nonmage) uses it.
The stone’s user concentrates for a second while crushing the spell stone
in his hand, thus casting the spell. At the beginning of his next turn, roll
against the spell stone’s Power. If the roll is successful, the spell is cast. If it
is failed, the stone is simply wasted. If the stone is crushed without the requi-
site second of concentration, it is likewise wasted.
The spell’s energy is included in the enchantment; none is required of the
user, who also may not opt to supply any power to maintain the spell.
Likewise, he may not cancel the spell once cast, although the creator of the
stone may specify a shorter duration than ordinary and may also invest
extra energy into the enchantment so that the spell will maintain itself. A
person may use only one spell stone per second.
A spell stone must be made from a jewel worth $10xP2 + $40xP, where P
is the maximum energy of the spell that may be contained.
Any spell except a Blocking or Enchantment spell may be stored in a
spell stone. Limiting Enchantments may be put on the stone. If the spell
stored in the stone requires that the caster know another spell (Counter-
spell, for instance), that other spell must be specified at creation time. It is
thus possible to create a spell stone that will counter one specific spell, but
it is impossible to create a generic Counterspell spell stone.
It is also possible to create spell stones which, when crushed, do not
cast the spell for the user, but on him!
Analyze Magic reveals which spell a spell stone contains, whether the
spell will be cast for or on the caster, how much energy was invested, etc.
(one question per casting).

Energy cost to cast: 20 times the spell’s casting cost, including
maintenance cost if so desired.
