Orbs for the Orbally-inclined

SunderedWorldDM says "orbs are cool and there aren’t enough of them", but also has a criticism for orb-centric adventure design, in the wake of my orbseeker class, which has changed the way games shall be played forever:

To which I say this: do not write what you can automate. Orbs are cool but they are, fundamentally, items. Scatter them thoughtlessly. Scatter them freely. I would recommend putting two magic orbs in a sizeable dungeon, or two per level in a very large dungeon. One orb should be in the first half, and easy to miss. The other should be further in, but obvious if encountered. Further, I would note the location or owner of a magic orb in major settlements and civilized locations, as well as the social relevance of such orbs. nonmagical orbs don't need to be planned for; let them appear as improvisation allows.

Now, a magic orb generator! Roll a d6 six times:

	substance	size	detail	power	domain	found in
1	glass	eyeball-size	shimmering flecks	cast a cantrip at will	doom	an alternate exit
2	wood	baseball	cracks	acts a wand of a relevant spell	valor	a trap
3	bone	cannonball	glimmering sheen	command domain	deception	a leader's belongings
4	bronze	beach ball	rotates by its own will	intelligent but immobile	exchange	an arcane area
5	iron	humanoid	etched symbols	is a level 1d4 mysterious orb	emotion	an ornamentation
6	living matter	a small room	foggy	contains a trapped miscreant	waste	the oddest room available
