Independence

Area
This spell can be used with any controlled creation or illusion. It lets the caster “program” the creation or illusion to move about, speak (if it can make sounds), and even react in predetermined ways. All this is done with no further concentration on the caster’s part; it does not count as a separate spell “on.” If faced with something for which it is not “programmed,” it may do nothing or (if an illusion) simply vanish, at the GM’s whim.

Duration: As long as the creation or illusion lasts.
Base cost: 2. Does not require maintenance.
Time to cast: As long as it takes the casting player to describe the instructions to the GM, or to read them aloud if they are in writing (writing them down will save arguments!). Complex instructions take a long time to cast.
Minimum 5 seconds.
Prerequisite: Simple Illusion.
