Editing TOTE:Rules (section)

====Criticals====

If you roll a 1 on your Paragon die and rolled at least 1 on your skill dice (even if you didn't select it for your result) you have rolled a Critical. Criticals don't automatically succeed, but they can trigger special effects (usually they trigger good effects when you succeed in the test, sometimes they trigger bad effects when you fail the test). Only skill tests can produce criticals.

The rules will call out many other times when successful or failed criticals will produce certain effects. Also, a hero's Special Abilities can also be triggered by critical tests. Certain actions may also automatically generate a Critical.
