|This spell causes the targeted magical effect to run through its duration at twice the normal rate. Usually this has the effect of cutting the duration in half, though in some cases (heat metal, for example) it can cause damage to be done more quickly. Note that only the magical field is affected, not any summoned or created creatures-- so this spell cannot be used to _haste_ summoned monsters, for example. The only effect on a summoning spell is to halve the duration.|
To affect any spell or effect cast by another creature, a caster level check must be rolled, just as in Dispel Magic. Also, only effects that can be dispelled with Dispel Magic are affected by this spell.
