Critical hits synergies
Crit chance on a weapon is the weapon’s own chance plus your Crit Chance stat; a crit deals round(hit × the weapon’s crit multiplier). Effects that trigger on a crit fire more often on high-chance weapons such as the Knife (50%) or Drill (50%). Structures cannot crit unless you own Pile of Books.
