Greater Detect Undead

With this spell, the caster can detect all undead within range. Range is equal to the caster's Intelligence score in miles. The detection is omnidirectional. The caster need not remain stationary. The spell indicates direction but not specific location, distance, or the type of undead-for instance, the caster might sense a small number of undead about ten miles north, a single undead creature about 100 feet to his left, and so on. The undead receive no saving throw against this detection, nor is the spell hindered by obstacles of any kind, save magical warding like non-detection.

The material component for this spell is a bit of earth from a grave.

Notes: Restricted to undead spellcasters of 11th level or higher; uncommon. This spell can be researched on in the Ravenloft setting.
