You see the world in patterns and precision.

## Tier 1 (Mathematics 1+)
* Calculated Risk – Mark a die as Effectful; on success, reroll 1 failed die on the next roll.
* Exacting Planner – You gain +1 die when predicting time-sensitive events.
* Counting Cards – Once per scene, tilt luck in your favor (force a target to reroll one success in a competitive roll).
## Tier 2 (Mathematics 2+)
* Trajectory Mastery (Mathematics/Archery) – You may reroll one failed die on ranged attacks with sufficient time to aim.
* Probability Bias – You may flip one die to its opposite face (1↔6, 2↔5, 3↔4) once per scene.
* Efficient Logistics – Once per journey, reduce supplies used by 50%.
## Tier 3 (Mathematics 3+)
* Predictive Model – Mark a die as Persistent; on success, allies gain +1 die to actions planned using your calculations.
* Structural Analysis (Mathematics/Mechanics) – You may instantly identify weak points in a structure, device, or siege engine.
* Battlefield Numbers – Once per scene, grant +1 die to all allies by predicting enemy movements.
## Tier 4 (Mathematics 4+)
* Improbable Gambit – Once per session, declare that an unlikely event occurs in your favor.
* Perfect Efficiency – You may reroll any failed die in a non-combat skill roll.
* True Calculation – When using dice pools, you may count a single success as 2 if it matches your pre-declared “number of fate.”
