and now there are abyssal beasts and profane beings assailing your corporeal and spuritual form you wish you'd had my orb instead

Yes, I was merely pondering my orb. The "beasts and profane beings" as you put it are simply arcane illusions.
An orb is used for more free flowing magic that requires your mind to wander as you channel. The spherical focus itself allows for the abstract to take form as you have more control over the weaves through hand and finger motions. Compare this with other foci such as staves, wands and swords; they have much more direction in which you channel arcane weaves.
Each focus is a tool and "discourse" surrounding orbs is utter nonsense. Such shortsighted commentary from an unlearned sorcerer.
