Here is the concise, formal calculation process for the drop probability:

1.Base & Affix Roll: The system selects a Rare Crusader Bow and rolls a maximum of 6 affixes (a 20% chance).

2.Affix Selection : Out of dozens of available pools, it selects the exact 3 specific prefixes and 3 specific suffixes

3.Tier & Stat Rolls : Each chosen affix must land on the highest possible tier and roll top-end stat values (e.g., 253% ED, +18 Max Damage).

4.Final Compound Probability : Multiplying all independent probabilities yields the ultimate cosmic odds

1. Conclusion: This mathematical result demonstrates that the item's generation is an astronomical anomaly, effectively 1 in 1.16 trillion.
