Also Seraph before I make my next post, remember that Ebon made a point to walk away from the cliff after he moved his shield between himself and Sapphire. Unless she intends to take out an even larger chunk of the cliff to take Ebon down.

I was under the impression that he altered his orientation around the Kingdom so that he was not as close to the cliff face as before like this:

First:
l(E)(K)

Second:
l  (E)
l  (K)

But besides that she's fired shells to liquefy the cliff on either side of the Kingdom and the area of effect of dust going off like that straight into the ground would be about a meter in either direction, so the section that's collapsing is about three meters across and goes from a foot in front of the Kingdom (give or take) to the edge. Not all of it liquefied but enough did that it's pushing the still solid rock off the cliff since it is effectively no longer connected to anything.
