It increases the chances of a half key, a dragon spear, and (possibly) a dragon half shield. However, it is debatable whether it has any other effect. --Eucarya 16:10, 5 November 2006 (UTC)

I found it interesting that you don't use a ring of wealth. Do you not believe in them? Two out of my three d drops have been when I wasn't wearing one, so I'm not sure how I feel about them myself. --Wowbagger421 22:47, 5 March 2007 (UTC)

I think ring of wealth only affects "second dice roll" type of drops. For example, if you were creating a new monster you'd say code it as Herb 20, Gem 5, Bronze longsword 3, Chaos runes 3, Air runes 6, etc... The engine then just packages this into a set of probabilities.

Now only "Herb" and "Gem" would involve a "second dice roll" - so you kill the monster, the drop selected is "Gem". Now then, the engine then has a second dice roll to determine the "quality" of that gem. Ring of wealth merely improves the odds on what type. In this specific example, "Gem", there's not just sapphire, emerald, ruby and diamond. In addition to this there's Dragon spear, Dragon half shield, and Half of a key. We know this because anything that drops gems can also drop those items. What your ring of wealth does is improve the chances of getting a "better" result on the second dice roll. It seriously doubt it will improve the chances of getting, say, a Dragon medium helmet, or any other Dragon armour item, and will probably not affect the rate that the unique slayer drops such as Rune boots or Granite mauls drop.

The way that the ring of wealth works was hinted at in one of the letters pages. --Eucarya Talk 08:27, 6 March 2007 (UTC)

Now then, whether there is "Other" second rolls happening I don't know (and if they are, ring of wealth helps). I suspect talismans are a second dice roll, but it is pure guesswork.

Great link and an amusing read. The second dice element only kicks in when there is a choice for the second item. So when killing the KQ, the first dice says "A chainbody", the second dice determines "rune" or "dragon". Obviously, a wealth ring helps in such a case. Same with seed drops, amount of coins drops and so on. The speculation clearly is on the category definition of the first dice. The odds improvement for the second dice roll also is uncertain. Most RS boosts are fairly small (5 to 10 percent maximum). --Miw 14:32, 7 March 2007 (UTC)

Why do you all assume that items are grouped by some common property for the second roll? It seems to me that the more likely scenario is that the first roll determines a drop list from a small choice of possible lists. For example, a monster might have have 3 lists, say, common, uncommon and rare, with probabilities of 70%, 28% and 2% respectively. Each of this lists would then have individual items. The rare list would have items like, for example, rune full helm, rune longsword and, say dragon med, with a 5% chance of a dragon med (making effective probability of getting a dragon med 0.1%). With wealth, the chance for dragon med from the rare lists would be boosted to say, 10%, giving effective probability 0.2%.

I seriously doubt that say, a dragon chainbody is part of a second dice roll. In fact, I suspect that most armour and weapon drops are defined in the first roll, ESPECIALLY where that monster is one of the only to drop it - so KQ will have both rune chain and dragon chain in drop list, rather than this being in a second roll. (Therefore, the ring of wealth would not increase your chances of getting a chain). I have some suspicions that there's a "slayer_coins" second roll defined from a lot of slayer monsters cos there's great similarity between the coin amount drops - 11...44..132..220..460 across a great deal of them. Another drop-set I think might exist is steel battleaxe...steel 2h....rune full helm (Jelly, Gargoyle, Nechryael). However, this could simply be someone copying a to b - it is impossible to tell whether a second dice roll is happening there.

Why have "second dice rolls" at all? It's simply convenient to do so in certain cases - instead of having to modify every single monster to give it a small chance of dropping a dragon spear, all they had to do was modify the "Gem roll" piece code so that immediately, any monster that can drop a gem can also drop a dragon spear. I also suspect that "second dice rolls" have fallen out of fashion - when they introduced crossbows, they seemed to modify a selected group of monsters, rather than the items being on a "second dice roll" that they could insert anywhere. Most monsters don't seem to drop similar armour/weapons every time - the steel battleaxe...steel 2h...rune full helm is the only link I can think of and that looks more a case of copy/paste rather than a second roll (only very extensive testing with/without a ring of wealth including several thousand kills could point to an answer).
