The ApplyEffectAtLocation() NWScript command causes the indicated effect to affect the indicated location for the indicated duration. Not all effects are appropriate for all duration types, but this command does not enforce that; it is left up to the scripter to avoid such things. This command is primarily used with visual effects and some areas of effect, as most other effects require an object to be sensible. (E.g., one cannot increase the intelligence of a location, as locations do not have ability scores.)
