Prerequisite: Spellcasting.
Benefit: You can create a magic item that stores a spell that
you know for a single use, such as a potion, a pinch of magical powder, or a
glass ball meant to release the spell when it shatters. Single-use items can
be used by any character, but always require some physical action, such as drinking
a potion, breaking a seal, or rubbing on a salve. Performing the action takes
a standard action and always provokes an attack of opportunity. The caster makes
all the choices about the parameters of the spell (such as the target) when
creating the item.
The purchase DC of a single-use magic item is the cost of the masterwork item
(minimum 10) + 7 + Magic Power + (Magic Power divided by 2 and rounded up).
Increase the purchase DC by 2 if the item allows the user to make some or all
of the choices about the parameters of the spell (for example, if using the
item allows the user to cast the spell on another creature).
Sample masterwork item costs: potion (purchase DC 10).
