Familiar

The spellcaster gains a familiar, which can
take the form of any small creature. A spellcaster
with a familiar gains +2 Health (write as a split stat).
If the spellcaster is ever reduced to 1 Health or less,
the familiar is destroyed.
At the start of the next game, the spellcaster reverts
to their normal Health, unless another Familiar
spell is successfully cast.
