The latest chapter in RWBY has provided a decent display of Ruby Rose's SE (Sliver Eyes) abilities beyond freezing/petrification that have been previously displayed.
I would like to see if someone could pixel scale the AOE of the SE attack in Volume 6 Chapter 6.
As for AP, the horde of Apathy that Ruby disintegrated are likely weaker than a standard Lancers. Due to Maria's statement and frail appearance. Although one of Apathy was shot by Ruby and was completely unaffected by it.
Assuming the Apathy are slightly weaker individually than the Lancers. Being put at a lower 9-B level. And a horde of Apathy are around 9-A then considering how much energy it takes to vaporize a wall.
Low Ball: 0.0000035850860420650095 x 27 (the show at any point) = 9.67973231E-5 ton = 9.67973231 x 10^-5 ton.
This puts the SE at low 9-A which is Small Building level.
High Ball: .005 ton x 49 (total seen in the tunnels) = 0.245 ton
That makes the SE AP about High 9-A which is Small Building level.
