Terrain editor cannot create cliffs?

I was wondering if the terrain editor could in some way create sharp angles or surfaces, much like the ones on cliffs. I find the terrain editor very limiting since it automatically smooths everything out.
Is there anyway I could use the terrain editor to do that?
Or will I have to model it?

Thanks in advance.

DONT USE raise/lower height

use paint height.(its the next thing over)

use the 4th brush only (or the 3rd to last I guess if you want to make it huge and paint a bunch)

set the height to how much higher you want the terrain to be than whats around it. for example just to try it out.

paint height. brush is the 4th one height is 40

click on the terrain once should look like a nice round cliff.
