Weave Fate

You weave the fortunes of creatures around you, taking control over their short-term fates. When you cast this spell, roll six d20s, and record each result. Then choose up to four creatures within range (other than yourself).

For the duration of the spell, whenever one of the targets makes an attack roll, ability check, or saving throw, you can choose to force it to use one of the d20s rolled in this spell, rather than the d20 roll it gets initially. You can do this after the roll is made, but before the DM confirms the result. Each roll may be used only once, and once all six d20s have been used, the spell ends.

At Higher Levels. When you cast this spell using a spell slot of 8th level or higher, you can roll one additional d20 and target one additional creature for each slot level above 7th.
