Ditching the seastone fired arrows would be appreciated, thank you.
I hope you're saying the explosions would be as big as the ones created by dials, because if you're saying they are dials, I kind of still have the same problem that dials are rare. I mean, more rare than seastone.
You don't have to specify what kind of explosives they are, but putting the radius of the explosion they cause, or at least the estimated damage (as in "small explosions") would be great.
