I thought you could add silver dust to granades to make them potent against werewolves and such. or is that only chunks or scraps of silver. You should probably get the platinum to repay the cold iron purchases.
It's chunks of silver, though I suppose I could use my lab to melt the dust and make the pellets necessary for some Silver grenades...I didn't think about that.
Archie spent about 250 GP on himself, buying up the scrap cold iron he needed to turn his Pellet Grenades into five Cold Iron Pellet Grenades. He feels a little screwed at the moment, because he could get that much just selling 5 of them to merchants, but accepts it as a cost of doing business at the last minute.
Next time, though, he'll go through his dwarven suppliers. At least they don't try to fleece him for all that he's worth...only half of what he's worth ;).
