This is actually one of Lying’s nastier spells.

Kinetic Disjunction has its origins in the earliest days of magic, before things were fully understood and long before they were fully worked out in practice. Those that experimented with telekinetic magic early on found themselves breaking objects into many pieces, often traveling in different directions as a consequence of imprecisely-applied kinetic energy.

Kinetic Disjunction is in essence that very same accidental phenomena harnessed to a sword edge of precision, and Lying is attempting to triage the shades so he can handle them better. Hence “divide and conquer”.

Whether this will actually help him or not is something we’ll see rather soon.
