Drop Rates
Am I allowed to add drop rate informations, extracted from the terraria source? Rynti 16:12, 1 June 2011 (UTC)
 * Yes, please do. I'll just ask that you start slow, and only do a few pages. Show the community what you want to do. 16:23, 1 June 2011 (UTC)

I've been working a bit on drop rates and have a couple questions. When I started 1 monster had a "Drop rates" section and 2 had "Special Drops", so I went ahead and used "Special Drops", but I like the sound of "Drop Rates" better. What is the proper placement? I think it should be at the top, after the initial text block but before videos and strategy. I noticed a handful of items listed drop rates on their pages. Should I deleted those and have it only on the monster's page? I think that would make it easier to update. Any opinions on the formatting? Originally I wanted to do a little table for it, but they like to use "if ... else if ..." a lot (like Demon Eye drops) and I thought that would get messy. I like having both the percent and the ratio in there (credit to whoever originally did Demon Eye). --KoreRekon 11:30, 6 June 2011 (UTC)
 * Hi.
 * I think it would be better to keep them on the monster page, as that is what the info should be found: It is a page about the monster. Pages about items should link to monsters that drop them, and players who want to know the drop rate should then go to the monster page
 * I think a table would indeed be too bulky, but I don't think it warrants entire sentences either. A simple bullet list is what would be best, IMO.
 * I think just simple "Drops" is the best title, as the drops may or may not be special. Further more, the section isn't entirely dedicated to the rates themselves.
 * Finally, I'm not a huge fan of the "else", as it is something strictly related to code. From an observer point of view, there is no "else": I think it would be better to just put the compounded "else rate".
 * So to summarize, I (IMO) think this would be best:
 * == Drops ==
 * Lens: 33.4% (1:3 chance)
 * Black Lens: 0.67% (1:150 chance)

 * I love that layout, simple and to the point. What about for multiple drops?  Something like:
 * 1-5 Spiky Balls: 50% (1:2 chance)
 * This part is going to sound horrible, but it's been a long time since I've used anything besides basic math. If there's one drop with 1:400 else another drop with 1:200, what is the formula to calculate the adjusted 1:200 drop rate?  It's sad how quickly I forget things I don't use. --KoreRekon 12:19, 6 June 2011 (UTC)
 * Yeah, that looks good.
 * If the first item is a/A, and the second item only drops when the first doesn't, at a rate of b/B, then overall, the second item will fall at (1 - a/A)*(b/B).
 * For the Demon Eye Example, that would be:
 * (1 - 1/3)*(1/100) = (2/3)*(1/100) = 2/300 = 1/150.
 * In your example, the exact value would be 399/80000, but I think it would be fine to put (&#8776;1/200). happypal (talk &bull; contribs) 12:29, 6 June 2011 (UTC)
 * Thank you. The (&#8776;1/200) actually answered my next question.  To continue the formula, would (1 - a/A)*(b/B)*(c/C) work for 3 daisy chained drops? --KoreRekon 12:44, 6 June 2011 (UTC)
 * It would be more like (1-a/ A )*(1-b/B)*(c/C). You can always draw a distribution tree if it helps. happypal (talk &bull; contribs) 12:51, 6 June 2011 (UTC)
 * Ordering of the drops, based on drop % (high to low?) or alphabetical? --KoreRekon 12:19, 6 June 2011 (UTC)
 * I'd say common to uncommon (so high% to low%) happypal (talk &bull; contribs) 12:29, 6 June 2011 (UTC)

You're correct on EoW's segments. About Shadowscale Armor drops... It's kind of a grey area. It will always drop a piece, but I thought we were more going for individual item drops and simplifying "else's" and other code complexities (like how Lens drop precludes a Black Lens drop). IE, Hornets/Man Eaters have a 1:150 chance to drop a random piece of Jungle Armor, I instead calculated individual pieces (1:450). --KoreRekon 15:48, 8 June 2011 (UTC)
 * Well, in this case, it isn't a detail though... each individual piece doesn't have an independent 33% chance to drop. The Eater of Worlds will never drop 2 pieces, or no piece. Overall, I think you did a great job, and what you did is good, but if breaking the rule for a page will make that page better, then so be it (IMO). This is your "project" though, so I'll let you have the last word, do as you feel works best. Don't be afraid to undo me - When it comes to page content, I'm just an editor. happypal (talk &bull; contribs) 21:51, 8 June 2011 (UTC)
 * Thank you for saying I did a good job. I couldn't have done it without your help. This is the first time I've ever edited a wiki, so I really don't want any sort of final say. While EoW will never drop 2 pieces nor no piece of armor, the Demon Eye will never drop both Lens's, a goblin will never drop 2 different items, a Hornet will never drop 2 pieces of armor, Dead Miner will never drop both of his items... In my opinion we should either go for simplicity (the chance of each individual item) or detail (if ... else ...).  Personally, I prefer detail, but that's much harder to present in a neat fashion. --KoreRekon 00:35, 9 June 2011 (UTC)
 * Also, thank you for adding the part about worm's segments. I had no idea how to stick that in there. --KoreRekon 00:38, 9 June 2011 (UTC)
 * That is true, but this default behavior of "never drops two items" does not apply to bosses: Each segment will always drop a scale and maybe some ore. Killing the worm will drop Potions and ores and a piece of the set. Under these circumstances, I find it leaves a little bit of ambiguity, and a bit more detail is required.

I have been removing the 1:1 ratio for a guaranteed item from the drops section in articles (meaning it only states "100% chance" instead of "100% (1:1 chance)" ), but KoreRekon has a valid point in that it doesn't look consistent once removed. Maybe we should stick to either a percentage or a ratio? It seems excessive to state both, especially in the 100% case. I prefer the percentage value, but I can see why some people would prefer the ratio instead (as an estimate of how many monsters he should kill for the item).
