Defend Distant Ward

By means of this spell, a wizard may choose a single spell of up to 4th level which he knows and cast it to protect a previously warded area or creature. When the spell is cast, the wizard chooses a location or being he has cast the 1st-level spell ward upon and ties the spell into it. If the ward is threatened, the spell then takes effect, targeted on whatever has disturbed the wizard's ward, but protecting the ward from any damaging area effects which might occur as a result of the spell.

The spell remains in effect until something triggers it by disturbing the ward. Minor grazing by herd beasts would not threaten warded land, so long as they were not too greedy, but a defiler attempting to draw energy from the land would be a threat and would set off the spell. Once activated, the spell is used up. If the wizard wishes to keep protecting the land, another defend distant ward spell must be cast.

The material components for the spell are a drop of water, a blade of grass and whatever is needed to cast the accompanying spell.
