Deadly Seeker

Deadly Seeker is a runic spell that appears in Ultima Underworld II.

Spell Description
This spell creates a magical bolt of energy which seeks out nearby living creatures. While these projectiles do not do a great deal of injury to a caster's foes, the Deadly Seeker spell is useful to magicians who wish to harry their enemies at a distance, as it does not rely on the aim of its caster to hit its targets.

Trivia

 * A specific sceptre of Deadly Seeker is necessary to complete a trans-planar trade with the mage Zoranthus, who requires it before they will give the Avatar a vessel containing an Air Djinn.
