Yes, but those are demons, not D’Orcs.
However, it is still true, in that whatever they do as sort of intrinsic is something they learned vs were born with.
The big point is that orcs, except for shamans, don’t have a lot of patience for spells, reading, talking stuff.
On the other hand, there are plenty of animage disciplines that are martial and don’t necessarily look like spellcraft. We will see more of this in OOA.
The shapechanging and giant weapons are a part of this. Remember the overly huge weapons that Talarius was marveling at? Things that should not be possible to be wielded by someone of that size?
