Crossing the Deadlands
Guts reflects a hero’s bravery. Characters are
often called on to make Guts checks when they
witness grisly scenes or encounter particularly
horrific critters. Guts is used in place of Spirit for
Fear rolls. The Marshal should refer to the Fright
table in Savage Worlds for the effects of failure.
Read more about Fear on page 97 in the Savage World rulebook if you want to determine how much of a factor it would be for your character.
