You can use greater refresh magic to prolong ongoing spells that have been cast on a creature or object, to temporarily bolster the magical abilities of a magic item, to prolong ongoing spells (or at least their effects) within an area, or to prevent another spellcaster from countering or dispelling a spell. Greater refresh magic can prolong spell-like effects just as it does spells. You can choose to use greater refresh magic in one of three ways: a targeted refresh, an area refresh, or an anti-dispel: Greater refresh magic can be used to defeat any counterspell.
