Familiar

A familiar is a normal creature that has been summoned to service by a sorcerer or wizard, after which it becomes a magical beast and gains new powers. They are magically linked to their masters, in some sense, practically existing as one being. All familiars have special abilities along with granting special abilities to its master.

Acquiring a Familiar
In order to aquire a familiar, the prospective master must first locate the kind of creature desired. This can be as convenient a task as visiting a city and purchasing a suitable animal within an appropriate shop. Some more exotic familiars usually take more effort to locate.

After locating the familiar, the master must arrange to keep the familiar nearby for the day-long ritual that binds the two together. Wise masters choose familiars that are friendly enough not to wander away, but sometimes the creature must be caged or otherwise restrained.

There are various rituals that bind familiars to spellcasters, ranging from a few gestures or chants to some drawings sketched on the floor around the pair – all repeated necessarily at intervals throughout the day. The ritual will fail if the intended familiar is hostile or unfriendly to the master, or has been charmed into amiability in any manner.

Empathic Link
Familiars and their master share an empathic link with one another that allows them to communicate, albeit in a limited capacity, at a distance of up to 1 mile (1.6 km). Only general emotional content, such as fear or curiosity, can be communicated; also, seeing as how familiars naturally see the world in a different light from their masters, a misunderstanding in translation is always a possibility. While not hampered by line-of-sight, the link is a supernatural ability so it ceases to function within an antimagic field; it also does not cross planar boundaries.

The empathic link makes the familiar an extension of the master's being, which means that when a familiar has been somewhere or experienced something, the master has the same connection to it as the familiar has.

Dismissal
Sometimes, a master will wish to be rid of a familiar, usually because they have suffered some debilitating injury or because the master simply wishes to acquire a new creature. To dismiss a familiar, the master simply wills it so, breaking the link that binds the two. Immediately on being dismissed, the familiar loses all abilities and becomes a normal creature of its kind, returning to life as such while suffering no ill effects, with the exception that it will likely be unable to remember most of what it experienced as a familiar.
