Level Scaling of Drop Rate

$\text{Drop Mean}_\text{Any Reward Tier} = \text{Drop Mean}_\text{Reward Tier 18} \times \text{Ratio}$

${\displaystyle \text{Ratio} = \begin{cases} \text{Reward Tier} \div 30 + 0.4 & \text{Reward Tier} \le 18 \\ 1 & \text{Reward Tier} > 18 \end{cases}}$

The Ratio for different Enemy Levels:
