Auspicious Scepter

Price 150 gp
Usage held in 1 hand
Bulk 1
Category simple
Group club
Damage 1d6 bludgeoning

This imperious +1 striking mace has a glowing orb in the shape of an eye set in its flanged head. When you succeed at a check to Recall Knowledge about a creature after you've dealt damage to it with the auspicious scepter, you learn one of its resistances in addition to any other information.

Activate—Fortunate Strike (concentrate)
Frequency once every 10 minutes
Trigger Your previous action was to Cast a fortune Spell that targeted a single ally

Effect Your luck magic lingers, allowing your target to find a weak spot in an enemy's defenses. The next Strike made by the target of the triggering fortune spell bypasses an amount of resistance equal to the spell's rank. This benefit is lost if it isn't used by the end of your next turn. If more than one type of resistance would apply against the attack, the attack bypasses only one—whichever would result in the highest amount of damage getting through, as determined by the GM.
