I'm looking for a word describing that something has been done without the help of tools, and an antonym, preferably both without an "un-" negation. They should fit in a classic high-fantasy setting (orcs, elves and wizards).
The specific use I'm looking for is to describe whether or not an elemental construct has been summoned with the help of a physical object, like an idol or a focus specifically made for that purpose (or a ter'angreal, for those familiar with the Wheel of Time), to help sustaining the construct. This focus is only there to anchor the construct to this plane of existence, to keep it from unraveling. Without it, the construct disintegrates quickly, with it, it can be kept alive for some time. The summoning itself is still managed by the mage.
The words "bound" and "free" give associations to the degree of free will exhibited by the constructs, rather than whether their existence is bound to an object. "Assisted" or "aided" falls very quickly into the "verbed-unverbed" category, and the former doesn't fit the fantasy tone very well.

The following terms may be suitable for differentiating between sustained and unsustained constructs or forces:
harnessed (adj.): derived from 'harness'(verb), to bring under conditions for effective use; gain control over for a particular end
ephemeral (adj.): lasting a very short time; short-lived; transitory
