AR: Objective Extrapolation

The World Through an Arcane Lens
Objective Extrapolation is arguably the second most popular "spell" – and itself has no external effect. Rather, once a magician has learned attenuation through a point source (usually through a wand), OE is a way of studying matter and the flow of energy via reflected magic through a process.

The same attenuation process that allows connection to the point source can facilitate awareness of arcane energy when in contact or in close proximity to a connected point source. By studying the reflected energy, the magician can attempt to magically recreate what they've experienced.

OE is the tool utilized for the majority of common-use spell invention. The act of learning an OE spell includes the first time in general principle (with a focus), plus a per-function analysis and recreation. OE is its own rated skill.

The base is OE + any applicable skill mod that would illuminate the mechanics of what is happening.

Seeking Illumination
OE seeks to mimic something real using magic. This is the ultimate utility tool for magicians and may take any mundane, common energy level form.

The most common OE-learned routine is creating light (via analyzing a lightbulb). Going beyond, it includes turning a wand into a screwdriver, ratchet, hammer, lighter (or a flame thrower), fan, broom, and so on.

OE is the primary introduction and learning tool for the arcane methods in the discipline of Conjuration.

Approximate OE target thresholds
Mundane processes can be stunningly simple or surprisingly complex. There can also be a very complex process of learning the limits and unintended consequences of replicating a mundane process (especially if has to do with the application of force).

Knowledge of the mundane physics or mechanics of the process will provide a bonus to understanding what is happening and how to recreate it magically. On more complex or esoteric mundane functions, the magic will mimic based on the approximate resonant frequency of what is happening, which makes it difficult (but not impossible) to replicate digitally-controlled activities.
