Hello and welcome to the forum!
The ring of wealth:
- does not affect the rare drop table
- does not affect the mega-rare drop table
- (MRDT, megararetable in the code)
- does affect the gem drop table
- (GDT, randomjewel in the code).
However this gets confusing for two reasons:
- The RDT has a 20/128 chance to roll the GDT
- The GDT has a 1/128 chance to roll the MRDT
- This chance is cut to 1/65 if you are wearing a ring of wealth. (The MRDT is what drops the dragon spear and the shield left half.)
So while the ring of wealth doesn’t directly affect the RDT, it will still have an effect when you land on the GDT from an RDT monster’s drop table.
And while the ring of wealth also doesn’t directly affect the MRDT, it increases the likelihood that you will land on the MRDT from the GDT.
It’s very confusing due to the amount of shared drop tables that exist and the ways in which they’re interlinked.
Put as simply as possible, the ring of wealth has an effect in two possible scenarios:
- Increases your chances of rolling loot on GDT (sapphires/emeralds/rubies/diamonds, rune javelins, half keys, chaos/nature talismans), and increases your chances of rolling the MRDT from the GDT.
It does not affect your rolls on the MRDT – it only affects the probability that the MRDT will be rolled at all (by removing the “nothing” drops from the GDT).
- Since the RDT rolls the GDT at 20/128, if you are wearing it while fighting RDT monsters, it will still take effect whenever your RDT roll becomes a GDT roll – go back to scenario 1.
However the RDT is not affected directly and therefore your chances for dragonstones or dragon med helms are not increased.
