DESCRIPTION
You create a bubble of magically enhanced time that consumes spells at a quickened rate. Upon casting this spell, all spells and spell effects within the time shield have their durations consumed at double their normal rate. Any spell with a duration measured in rounds or minutes, whether beneficial or harmful, is affected (spells measured in hours, days, or longer are shortened imperceptibly). Creatures affected by spells cast outside a time shield that enter the time shield have their spells consumed at the increased rate. Upon leaving the time shield, the creature’s spells again decrease at their normal rate.
Even spending only a portion a round within a time shield causes spells to expire at an accelerated rate. Thus, if a creature begins and ends its turn outside a time shield but passes through the area of effect in the interim, any spells that affect the creature lose 2 rounds of duration that round.
A time shield cannot affect another time shield, thus the spell has no effect on other instances of this spell.
