Duration types for ApplyEffectAtLocation() and ApplyEffectToObject() functions.
|| Instantaneous. This would apply to any effect that is both immediate and permanent and cannot be removed. EffectDamage would be one example, as well as any of the 'fire-and-forget' visual effects.
|| Permanent duration. This is as it sounds... the effect lasts until removed or dispelled
|| A temporary duration means that the effect must have a duration specified in the command (and is the only time this is so). Once the time has expired, the effect will be removed.
