Think of all impact damage having 2 free bonus statuses
- Exhaust / Stamina Drain when hitting any part of the body. When it procs, it mini-staggers it and drains a chunk of a monsters stamina. Monster Stamina is drained by all actions anyways, which once empty, kneecaps it's moveset, prevents it from enraging (unless it's already enraged, at which point the exhaustion is delayed until the enrage is over) and slows it down until it manually recovers by moving to another area and eating / drinking or times it out.
- Stun / KO when hitting the head. This acts as a separate category of topple, with it's own buildup threshold / resistance buildup, separate from the usual topples that is built up by partbreak damage (not parts broken, just blanket partbreak applied).

They're different components, because all Impact deals Exhaust + KO, but some things like CB phials and Bow coatings deal Exhaust but no KO. This is Impact's tradeoff for not getting to cut tails (as well as usually better hitzones).
