Abjuration
|
|||
|
|
Level: Clr 7, Protection 7, Sor/Wiz 6
|
|||
|
|
Components: V, S, F/DF
|
|||
|
|
Casting Time: 1 standard action
|
|||
|
|
Range: Up to 10 ft./level
|
|||
|
|
Area: Up to 10-ft.-radius/level emanation centered on you
|
|||
|
|
Duration: 1 round/level (D)
|
|||
|
|
Saving Throw: Will negates
|
|||
|
|
Spell Resistance: Yes
|
|||
|
|
|
|||
|
|
An invisible, mobile field surrounds you and prevents
|
|||
|
|
creatures from approaching you. You decide how big
|
|||
|
|
the field is at the time of casting (to the limit
|
|||
|
|
your level allows). Any creature within or entering
|
|||
|
|
the field must attempt a save. If it fails, it becomes
|
|||
|
|
unable to move toward you for the duration of the
|
|||
|
|
spell. Repelled creatures<65> actions are not otherwise
|
|||
|
|
restricted.
|
|||
|
|
|
|||
|
|
They can fight other creatures and can cast spells and
|
|||
|
|
attack you with ranged weapons. If you move closer to
|
|||
|
|
an affected creature, nothing happens. (The creature is
|
|||
|
|
not forced back.) The creature is free to make melee
|
|||
|
|
attacks against you if you come within reach. If a
|
|||
|
|
repelled creature moves away from you and then tries to
|
|||
|
|
turn back toward you, it cannot move any closer if it
|
|||
|
|
is still within the spell<6C>s area.
|
|||
|
|
|
|||
|
|
Arcane Focus: A pair of small iron bars attached to two
|
|||
|
|
small canine statuettes, one black and one white, the
|
|||
|
|
whole array worth 50 gp.
