In Spellfire (and other novels) we often see scrying orbs floating, and being summoned/dismissed by command words- is this a property made in those particular orbs, or a spell applied to them (for example a version of instant summons)? many thanks A property enchanted into those orbs when they're magically created. However, they are what 5e terms "attuned." Meaning, if you're not the individual (or in some cases the SORT of being) an orb is "made for," you have to cast the right spell to enact control over such an orb.
