Once cast, trust in the gods lasts for one day or until used. When it is used, the caster may select any single die roll she is about to make, and the result will automatically be a success (the exact result desired by the caster). The use of this spell must be declared prior to the die being cast. The experience point loss accrues regardless of whether or not the spell is discharged.
Experience point cost: 500 experience points per casting.
