Separate Binding

If a monster arrives unbound or is come upon unexpectedly, it may be bound on the spot.  The caster must know the Summon/Bind spell for that type of thing, and must spend a game round chanting before the thing can be bound.  The caster then matches magic points against the thing’s magic points on the Resistance Table. Failing, chant the Bind portion of the spell again.  Each cast of the binding costs 1 Sanity Point but no magic points.  A binding cast works on only one creature at a time.
An attacking creature cannot be bound by the person fighting, but it could be bound by a person able to hold back from the fray.  A creature presently bound cannot be rebound until its present command is completed.  A creature to be bound must be visible to the caster and within 100 yards.
