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
