Duality Surge: Echo of Insight

Tapping into cold, analytical brilliance, you conjure a brief window of foresight. Arcane sigils briefly shimmer around your target, guiding their next move with uncanny precision.

Target yourself or one creature within 60 ft. They gain +1d4 to their next saving throw or ability check before the end of their next turn.

At Higher Levels.
When cast using a spell slot of 2nd level or higher, the bonus increases to +1d6 (2nd), +1d8 and +3 AC (3rd), and at 4th level you may affect two creatures and apply the bonus to attack rolls as well.
