From Explorer’s Guide to Wildemount, the Chronurgy Wizard’s Chronal Shift ability says:
You can magically exert limited control over the flow of time around a creature. As a reaction, after you or a creature you can see within 30 feet of you makes an attack roll, an ability check, or a saving throw, you can force the creature to reroll. You make this decision after you see whether the roll succeeds or fails. The target must use the result of the second roll.
Using the adult red dragon as an example, Legendary Resistance reads:
If the dragon fails a saving throw, it can choose to succeed instead.
Specifically, here is the scenario:
- Wizard casts saving throw spell on Red Dragon
- Red Dragon rolls the saving throw and fails
- Red Dragon expends one use of legendary resistance to succeed on the saving throw
- Wizard uses their reaction to use Chronal Shift to force the dragon to reroll the saving throw
- Red Dragon rerolls the saving throw and fails
- Red Dragon expends a second use of legendary resistance to succeed the saving throw
In particular, is step 4 of this scenario a valid use of the Chronurgy Wizard’s Chronal Shift ability?
