I see you have been misinformed a bit about seastone. It doesn't work as an instant DF nullifying, it works as if it was the sitting water solidified. If it touches a DF user, their powers are nullified, however, that does not mean it nullifies any DF attacks that touches seastone.

Daaaamn. That screws me over then.
