You could make a magic cannon with this.
With a block of orichalcum. Make some sort of circuit that would cause the orichalcum to touch the Silver Output when you needed..
One cubic foot would mean 100d6 points of damage.
Now, if you automated that with an Intelligence..
Sentry Cannons. Hehehe..
I want to make a ship with this. A huge flying ship with cannon and gods only know what else.
I can't express how much I love this right now. I haven't been this excited since I discovered GURPS.
