D2 Base Drop
From Basin Wiki
Recursive Probability Table
Drops work as follows:
For a given Equip TC, there are (usually) 4 pairs of weapon and armor TC and a 'drop' possibility. The probabilities (Px) are summed (S) for the whole class and a random number is generated from 1 to S to determine the drop. If the number generates another Equip Class, then the process is repeated.
for Act 3 Equip A there is a total of 136. therefore:
2/136 chance of weap15
1/136 chance of armo15
6/136 chance of weap18
3/136 chance of armo18
14/136 chance of weap21
7/136 chance of armo21
2/136 chance of weap24
1/136 chance of armo24
and 100/136 chance of dropping to Act 2 Equip C
When you do the calculations recursively, you get the probabilities shown these tables: D2_Base_Drop_2
