I only ever remember him using the Diving Gear once and it gives him the same name and abilities as Vali's, so I don't know what "new ability" your talking about

Although I have this idea for a new ability, he uses his Dividing Gear to absorb the Power of Destruction and is able to use the power himself.

In my openion, in a flame-like effect thus giving him crimson coloured dragon flames, I just figured how since Saji had black coloured dragon flames.
