How would I recreate this arched pillar from Vanishing Realms? This is from the first room in Vanishing Realms:



The part I am concerned with is the top section that goes from a straight column to this kind of splayed out effect, not sure of the correct term. Anyways in SolidWorks you would loft this in a couple of seconds, how can I do this in Blender?

Thanks in advance.
Final result:



Modeling:

It's extremely simple.

Just add a Cube. Go to Edit Mode. Select bottom face and extrude (hit E) it down in the Z axis, after extrude - scale it down (hit S). Repeat for every segment.



After that make object Smooth and add Autosmooth or Edgesplit Modifier.
