Dheryth's Spell Support
(Abjuration)

Range:  0
Components:  V, S
Duration:  Special
Casting Time:  6
Area of Effect:  Special
Saving Throw:  None

This spell is cast immediately before any other spell which has a duration (there are some exceptions - see below). It doubles the casting time of the other spell and adds verbal and somatic components of its own. The effect of spell support is to make the other spell totally immune to dispel magic for its normal duration. Spell support itself is not dispellable, and if it is cast in conjunction with permanency, the net effect is to make the other spell both permanent and undispellable.
Certain spells (at the DM's option) may not be supported, including at least the following ones:
•	anything wish or limited wish related,
•	prismatic wall and prismatic sphere,
•	Otiluke's resilient and telekinetic spheres,
•	forcecage and forcecube,
•	anything gate related,
•	magic jar, and
•	temporal stasis.
Spell support in no way reduces the efficacy of Mordenkainen's disjunction, nor does a single casting protect any additional spells that may be active in the same space.
On permanency, there is a 10% chance per year that the spell support will fail, leaving the permanency intact but unsupported. The wizard has now way of detecting that the spell support has failed.
