'DENY SUMMONING' (382)

Syntax: cast 'deny summoning' [<target>] [mana]

When casting this spell, the Conjurer can decide to extend its natural
duration by channeling additional mana into the shield.  When cast, the
Conjurer surrounds himself (or another who trusts him) with a mystical 
dimensional barrier in order to make himself (or the target) immune to 
the summoning spells of others.  However, this also means the target of
the spell loses all other means of inter-dimensional travel during its 
duration.
