Fixes the other half of the crusher bug (#84028)

## About The Pull Request

Fixes #83906

So when I test the first issue I just whacked the guy and the checked VV
to see if it was tracking damage at all then I called it a day, turns
out while it was applying damage it was actually negative damage from
the crusher itself so while the final number of damage dealt may look
like "2500" the tracker tracked like "1400".

(I mean that's still a pretty interesting statistic is shows that the
crusher itself, with none of its special effects, does just under 60% of
the total damage dealt, so cool)
