Help Dispel Magic Cancellation Abort Spell

Syntax cast 'dispel magic' <character>
       cast 'cancellation' <character>
       cast 'abort spell' <spell>
		 
The first two spells remove magical effects from the target. Dispel   
magic has a reduced chance of working, and is considering an attack 
spell.  Cancellation can only be used on allies, but is much more
effective and does not provoke attack.  Unfortunately, the spells
do not discriminate between harmful and benign spells.

Abort spell is only for Cleric and Mages, people who know the 
internals of spells. It allows them to disable one specific spell.
Unfortunatly it requires quit a lot of concentration and it only 
works for the spells they know themself.

The chance of dispelling is based on the level of the spell.  
Permanent spells (such as mobile sanctuary) are much harder to
remove.  Not all spells may be dispelled, notable examples are
poison and plague.
