Do critical hit spirits also stack with Hero's passive of having a chance to crit on f. smash?

Solution 1:

I suppose you would be technically correct to say that spirit crits and Hero smash crits "stack multiplicatively". But it would be more correct to say that they are entirely separate mechanics that do not directly interact with each other:

  • Spirit crits give a percent chance (5% or 12%) for any attack's damage to be multiplied.
  • Hero's smash crits give a percent chance (12.5%) for his smash attacks to use a different set of hitboxes that deal more damage to enemies and have other minor attribute differences.
