Keyed Spell Items
   A Sneak Peek From Book of Hallowed Might II: Portents and Visions

   This excerpt is taken from Chapter Five: Mountain of the Voice.  At
   the priory there, followers of the Divine Voice have learned to make
   a new classification of magic item....

   Keyed spell items are a whole new type of magical item, of use only to
   spellcasters. Each keyed spell item is infused with the essence of a
   single spell, making it easier for a spellcaster to cast that spell.
   Sometimes they further enhance that specific spell.

   A cleric with a keyed searing light bracelet does not need to prepare
   the searing light spell. Instead, he can use any of his 3rd-level
   spell slots to cast searing light in the same way that he could switch
   out a prepared 3rd-level spell to cast cure serious wounds. A keyed
   spell item allows the caster to spontaneously cast the spell it is
   keyed to, using the power from another prepared spell. The prepared
   spell is lost. Keyed spell items do not allow a caster to cast more
   spells in a day, but they provide versatility.

   In order to use a keyed spell item, a caster must have on his spell
   list the item's keyed spell. So a druid cannot use a keyed teleport
   ring or a keyed divine favor amulet.

   Spellcasters who do not prepare spells can use keyed spell items,
   casting the spell keyed to the item as if it were one of their spells
   known. However, activating the item requires a slot one level higher
   than normal. So a sorcerer with a keyed fireball headband must use a
   4th-level slot to cast fireball.

   Keyed spell items are almost always objects that take up a standard
   position on a caster's body: a bracer, cloak, belt, vest, necklace,
   headband, and so on. Those that do not fit a standard position, such
   as a wand, must be in the caster's hand at the time of casting.

   The cost of a keyed spell item equals the level of the keyed spell
   squared, multiplied by 100 gp. So a 1st-level keyed spell item costs
   100 gp, a 2nd-level keyed spell item costs 400 gp, 3rd-level costs 900
   gp, and so on. A keyed spell item with a 0-level keyed spell costs
   half as much as a 1st-level item: 50 gp.

   Obviously, keyed cure spell items appear only very rarely, since most
   casters who could use such an item can already spontaneously cast cure
   spells.

   Enhanced Keyed Spell Items

   Sometimes, a keyed spell item not only allows a character to
   spontaneously cast a specific spell, but, whenever he casts the keyed
   spell (whether it's prepared or not), the item gives it extra power.
   The enhancements below offer some suggestions.

   Appearance: Using the keyed spell item changes the appearance of the
   keyed spell's effect to something specific. For example, a protection
   from evil keyed spell gives the recipient the aura of swirling golden
   shields. Cost: +100 gp.

   Area: This enhancement doubles the area of a keyed spell whose area is
   described as a physical space (as opposed to Personal, single target,
   etc.). Cost: +500 gp/spell level.

   Duration: This enhancement doubles the duration of a keyed spell whose
   duration is something other than Instantaneous. Cost: +300 gp/spell
   level.

   Potency: This damage-inflicting keyed spell deals 50 percent more
   damage than normal. Cost: +1,000 gp/spell level.

   Range: This enhancement doubles the range of a keyed spell whose range
   is something other than Self or Touch. Cost: +300 gp/spell level.

   Spell Specific: Some items have enhancements that apply to the
   specific parameters of a spell, such as the speed of levitation or the
   number of creatures a sleep spell can affect. Generally, the item
   shouldn't increase the spell's overall power by more than 50 percent.
   It should not change one spell into another spell (such as altering a
   lesser globe of invulnerability to resemble a greater globe of
   invulnerability). Cost: Varies.

   Some example specific enhanced keyed spell items include:
     * Keyed Blur Cloak: The keyed blur spell offers a 30 percent miss
       chance. Cost: 1,400 gp.
     * Keyed Commune Headband: The caster is allowed an additional
       follow-up question at the end of the spell, before which she can
       take 5 rounds to contemplate and confer with others. Cost: 4,000
       gp.
     * Keyed Darkness Gem: The keyed darkness spell allows the caster to
       see within its confines. Cost: 2,400 gp.
     * Keyed Detect Evil Lenses: The keyed detect evil's 1st-, 2nd-, and
       3rd-round information come all at once. Cost: 550 gp
     * Keyed Divine Favor Amulet: The keyed spell's damage bonus also
       applies to spell damage. Cost: 800 gp.
     * Keyed Fly Belt: The keyed fly spell's move rate increases to 90
       feet. Cost: 1,900 gp.

   The enhanced factor of these items is always very specific to their
   keyed spell. Thus, obviously, there are no keyed searing light items
   that increase duration, because the spell's duration is Instantaneous.

   Universal Keyed Spell Items

   The most powerful type of keyed spell item is the universal keyed
   spell item, which allows casters of any class to spontaneously cast a
   specific spell, regardless of whether it is on their spell list or
   not. So a cleric with a universal keyed magic missile glove could use
   any of his 1st-level spells to cast a magic missile, even though it is
   strictly a sorcerer/wizard spell.

   The cost of a universal keyed spell item equals the level of the keyed
   spell squared, multiplied by 2,000 gp.

   Making Keyed Spell Items

   Characters use the Craft Rod feat to create keyed spell items.
   Creators must be able to cast the spell to key it into the item.
