Prerequisites: Caster level 1st.
Benefits: This feat allows a creature to create spell-trigger items which casters can use as if they were their own sphere abilities. A creature must possess a spell engine’s base sphere, or else must activate the spell engine through the Use Magic Device skill.
The most common form of spell engine is a wand; a handheld stick usually between 5 and 12 inches long that the caster points to direct the magic. However, a spell engine can take any form.
A spell engine contains a limited amount of casting ability, which can be activated by the one wielding the spell engine as a standard action, as if the magic were their own. A spell engine possesses a base sphere, a caster level, and a small pool of spell points. The spell engine uses its own caster level and spell points to fuel its casting ability; under normal circumstances, a caster cannot spend their own spell points or use their own caster level when activating a spell engine. If a spell engine’s effects call for a saving throw, the DC is equal to 10 + 1/2 the item’s caster level.
Once per day, a caster whose caster level is at least equal to the spell engine’s caster level may spend one of their spell points to restore 1 spell point to the spell engine. A spell engine may only have one spell point per day restored in this fashion, regardless of how many casters attempt to do so.
The simplest spell engine a crafter may create contains a base sphere, 1 spell point, and a caster level of 2. This spell engine has a base price of 1,000 gp. When a crafter increases a spell engine’s caster level (to a maximum of their own), for every 2 caster levels a spell engine gains, the crafter may place an additional magic talent into the spell engine, or may increase the spell engine’s maximum spell point pool by 1. A crafter must possess each talent to be placed in the spell engine, or else must have access to that talent through another caster. Likewise, if a crafter possesses a sphere-specific drawback for the spell engine’s base sphere (or simply wants to create a focused spell engine), that spell engine also possesses that sphere-specific drawback, and gains either a bonus magic talent or a spell point in exchange.
A spell engine may contain an advanced talent, but must possess that talent’s minimum caster level, as well as all of its prerequisite talents. A spell engine may be used to meet the prerequisites for creating other magic items.
A spell engine’s pricing is determined by comparing it to Table: Spell Engine Pricing.
