The formulas for both rewards have a midpoint of {{IL|Watchful}} 190, and a scaling factor ''k'' of 0.1. In other words, all formulas use a Logistic basis of:
<math>L(W) = \frac{1}{1 + e^{-0.1 \times (W - 190)}}</math>
<br />
This basis function goes from 0 to 1 as Watchful increases. They differ in the heights and y-offsets:
*{{IL|Primordial Shriek}}: 1 + 200 × L(W) (i.e. height of 200, y-offset of 1)
*{{IL|Trace of the First City}}: 1 + 11 × L(W) (i.e. height of 11, y-offset of 1)
