Flambeau's Bloody Greeting
Muto Herbam (Terram) 8 (Base 4, R: Touch, D: Momentary, T: Individual, +3 Restricted Trigger)
Two dozen cherry stones in a sackcloth pouch, collectively enchanted as a charged item. When any person or animal which does not live in the enchanter's covenant steps upon the stones, each seed simultaneously transforms into a rough iron caltrop for a brief moment. Trespassers with soft shoes must pass an Athletics+Quickness stress test of 12, or take +4 damage. A horse who is wounded by caltrops may be frightened and routed without an experienced rider's help. The lab text for this item includes the cherry's bonus to causing bloodshed, though it has not realized its full potential. To the surprise of the young enchanter, they managed to invest two charges into what they assumed would be a single-use trap.
Originally named Flambeau's Christmas Greeting, the apprentice's parens took umbrage at the casual blasphemy and spanked the boy for the rest of the night. Quite unfortunately, his shield-grogs liked the original name better. This started a long tradition of threatening enemies by sending them dried fruit for Christmas, to the confusion of every other covenant in the area.
