This magical rod is indistinguishable from a horseman’s mace. When magic is detected for, it will reveal a dweomer of Divination and Abjuration.
The rod bestows +1 to the possessor's die rolls for being surprised, and in combat the possessor gains -1 on initiative die rolls, and a +1 "to hit".
If it is grasped firmly, the rod will enable the concentrating character to detect illusion. The use of the detect power expends one charge in the rod.
There are likely other features yet to be discovered.....
