Spell changes: dispel magic, magic blast

These incantations used to give the caster an all-or-nothing chance of
removing magical effects (such a defensive spell) from the target.

Now there is also a chance that the target spell will be dispelled in part,
losing some of its effects. For example, the victim might lose some, but not
all, of the extra defence granted by 'shield'.
