Distorting Fate

This spell allows you to change fate. When you cast this spell on yourself or another creature you choose Woe or Weal.

Woe allows you to make a creature reroll the die for a saving throw, ability check, or other and they must take the new roll but this is before you know the outcome and they have a disadvantage on this roll.

Weal allows you to make a creature or yourself reroll the die for a saving throw, ability check, or death saving throw, and you/they have to take the new roll, unlike Woe you can do this after the outcome of the roll.

Now, this spell doesn't come without its downsides. Once you've cast this spell the DM must roll a die to see what divine being might take notice of you. The DM then decides on the DC out of a d100. If the DC has been failed however far away it is from the DC will change the challenge of letting that god leave the caster alone with or without a consequence.
