Thalia Grace, from the Percy Jackson series, wields a collapsible copy of Aegis. I.E, a shield. It has a very realistic engraving of the medusa head on it. It doesn't turn anyone to stone, or anything. But, foes don't like it, meaning (to me, anyway) that it either has an intimidation attack of its own, or somehow augments Thalia's intimidation.
How would you model this aspect of the shield? Simply give it an aspect "Scary shield" which can be tagged to apply to an entire zone?
And if anyone wants to write up the shield, that would be cool too.
