I was curious about this new ability... Aesthetically.. Is it lightning? A few bolts? Or something else? Hard to tell in the videos...Does it completely negate crushing darkness?
I'd say it sorta sucks in Force lightning on the target and then explodes in a flash of light.
It is meant to be a replacement for Crushing Darkness, as they both share the same cooldown. You can, however, have both Demolish and Crushing Darkness DOTs on a target through well-timed use of Raze. I can't say for sure if that is recommended, though.
