Is it possible to inscribe Undead Ward on an item, and if so what would the effect actually be? For example, inscribing it along the edge of a shield, around a belt, or around the outside of a helmet or circlet? Or along a staff, club or sword?
Unlike Magic Circle, which specifies it is inscribed on the ground within the rules text, the only part of the text of Undead Ward which suggests this is the fluff text.
The ritual Undead Ward has text as follows:
Undead Ward The line you etched in the floor shines like ivory in moonlight, and the skeletons stop advancing.
Component Cost: 35 gp Market Price: 130 gp Key Skill: ArcanaLevel: 3 Category: Warding Time: 30 minutes Duration: Until broken
You create a magical barrier against undead creatures. This barrier can be a closed circle, with an inscription time of 1 minute per square inside the circle, or a line, requiring 1 minute per 2 squares of length. An undead creature whose level is lower than your Arcana check result – 10 cannot pass through the barrier, affect creatures through the barrier, or affect the barrier in any way. Any other undead creature takes radiant damage equal to your Arcana check result when passing through the barrier, but doing so breaks the barrier and ends the effect. Any creature able to pass through the barrier can take a standard action to obscure the inscription and thereby break the barrier.
