Living Monolith abilities

[Mike Lindner]

I am planning on taking levels in the Living Monolith prestige class. I noticed that Ka Stone and Master Ka Stone are supernatural abilities but Greater Ka Stone is spell-like. Is this correct or was that 'p' supposed to be a 'u'? If it is right, I am interested in understanding why that is. Is it just a balance issue?

I'm pretty sure that's a typo, and the Greater ability should also be Su.

I just noticed an inconsistency on Fortified Flesh. The text description states it gives DR/adamantine, while the table on the following page says DR/-. Does anyone know which is should be?
