I'm kind of skeptical that you're remembering correctly given there's absolutely nothing in the help file to suggest wisdom is important:

Those warriors who honed their reflexes to the precision demanded by the
technique of Space Between Heartbeats were said to be faster than thought.
Though not especially forceful, their strikes were masterpieces of rapid
acceleration, beginning and ending in one instant. Their hallmark technique
was to hover near their foe, daring them to take their eyes off them for
that one instant they coveted. Foes who distracted themselves with picking
up items, rummaging through packs, fumbling with backup weapons, and the
like while fending off these warriors often found themselves on the receiving
end of strikes they never saw, delivered in the Space Between Heartbeats.
