eye, inst.
This spell is only effective against another wizard. The caster
is able to pull a formulaic spell from the target's mind and cast
it, in the next round only, using the target's scores in the
relevant arts. The caster knows immediately the name of the spell
he has borrowed, and if he is trained in the appropriate theory,
he knows all its effects. If the spell is not used in the next
round, it is lost to the caster, but in any case, the target may
not cast the borrowed spell in the round that the caster has it.
If the target was preparing to cast a spell, that is always the
spell borrowed. Otherwise, the caster may choose a spell known to
him or take a spell randomly chosen from those the target knows.
