  • The granted total bonuses at each minute throughout the game are calculated as follows:
\pagecolor{Black}\color{White}m \in \mathbb{R}_{\ge 0} is the number of elapsed minutes throughout the game.
\pagecolor{Black}\color{White}k_{AP} = 8.0 is the AP multiplier.
\pagecolor{Black}\color{White}k_{AD} = 4.8 is the AD multiplier.
\pagecolor{Black}\color{White}S\left(m\right) = \sum_{s=0}^{\left\lfloor \frac{m}{10} \right\rfloor}{s} gives the stacking term.
\pagecolor{Black}\color{White}B\left(k,m\right) = k \times S\left(m\right) gives the bonus term.
Bonus AP: \pagecolor{Black}\color{White}B\left(k_{AP},m\right) = k_{AP} \times S\left(m\right).
Bonus AD: \pagecolor{Black}\color{White}B\left(k_{AD},m\right) = k_{AD} \times S\left(m\right).
Example for bonus AP (\pagecolor{Black}\color{White}k_{AP} = 8.0) at 32.5 minutes (\pagecolor{Black}\color{White}m = 32.5):
\pagecolor{Black}\color{White}B\left(k_{AP},m\right) = B\left(8.0,32.5\right) = 8.0 \times S\left(32.5\right) = 8.0 \times \sum_{s=0}^{\left\lfloor \frac{32.5}{10} \right\rfloor}{s}
\pagecolor{Black}\color{White}= 8.0 \times \sum_{s=0}^{3}{s} = 8.0 \times \left(0+1+2+3\right) = 8.0 \times 6 = 48.0.
Example for bonus AD (\pagecolor{Black}\color{White}k_{AD} = 4.8) at 21.5 minutes (\pagecolor{Black}\color{White}m = 21.5):
\pagecolor{Black}\color{White}B\left(k_{AD},m\right) = B\left(4.8,21.5\right) = 4.8 \times S\left(21.5\right) = 4.8 \times \sum_{s=0}^{\left\lfloor \frac{21.5}{10} \right\rfloor}{s}
\pagecolor{Black}\color{White}= 4.8 \times \sum_{s=0}^{2}{s} = 4.8 \times \left(0+1+2\right) = 4.8 \times 3 = 14.4.
Python 3 function which computes \pagecolor{Black}\color{White}B\left(k,m\right):
def gathering_storm_bonus(k, m): return k * sum(range(m // 10 + 1))
