Sticky of Weekly (?) Gate Breakdown?
I am not sure how often the gates are reset for precisely what levels are available in them, but would someone who has experience with them be able to generate a wiki or sticky breakdown of what each level is?
For example, right now there is a gate with Iron Edge Arena: Robo Rampage available on the first level. In here there are lots of turrets and robot enemies, which I have found to have a high droprate for blue shards. Later in the same set is Deconstruction Zone: Savage Salvaging, which has lots of gremlins, and I assume that means a chance to drop the Gremlin Gizmo (have gotten 1 from one of them, but in a deeper level).
Having some knowledge about the levels, even just "Lots of Spike Traps," "Mostly Wolver Enemies," "No Gem Supply Location" or "Contains an optional Boss Gate" would be really nice. Having a "High chance of Blue Shards/Gizmos/Whatever" as well would be awesome.
Just seems like it ought to be possible to compile, and have available so that you can make the most out of your trips into the dungeon by choosing a route likely to yield what you need.
Do you mean that (for instance) the first 2 options for Gate 3 Depth 1 aren't always those specific 2?
I know that the elevator swaps between which one of those 2 it will send you to every 2 or 3 minutes. But every single time I have looked, it is the same 2 options to wait through. So you can quite easily decide between them and take your favorite.
I read that in Tier 2 and Tier 3 the elevators cycle slower, so selecting a specific route there isn't nearly as easy. But by the time you are in those Tiers you will have developed a fair intuition for what is on each floor (I just got to them and have a fairly decent idea of what I am looking for now). But I am looking to see if a resource that I wish I had as a first/second day player could be generated for future newbies.
The wiki breakdown is pretty nice, but you have to already be fairly familiar with the game for it to make ANY sense at all. And willing to invest the time in decoding things. So if a player who is very casual, or only on their first couple of days playing can go to a single location to know "If you suck at fighting Wolvers, don't go here!" and such, then it would be a great boon to retaining new members of the community.

If you want to farm for a specific item you'll need to find what it drops from. Then you'll need to find that specific element theme + monster theme + strata level that you can access and then spend in essence a very long time trying to skew elevator destinations so that you end up in your desired level. THEN you need to run it countless times because the specific monster you want might not spawn very often in it. Even if it does spawn the majority of the time you are still trying to farm a rare material which depending on your luck it could not drop at all. Then the gate changes and you don't have access to it anymore. Well that's okay because the majority of rare items are dropped by different monsters so you can start the whole process over again and try your luck farming it again. Assuming you are only farming for 1 specific item and not multiple items which sounds like it's less complicated but then you have to choose which one to farm for and what new items you can farm for in new gates. There are also potentially 182 different gate combinations which you'll have to start from depth 0 for each new one if you don't want to pay extra to skip down a tier or two.
Having taken it out of context no "new" player is going to sit and read and memorize every different level, the monsters, their drops and why they would even care about this information. They just want to play the game and so should you. The best you can hope for is "Oh this gate has 5 poison strata and glancing over the gate map it seems it's all wolvers. That really sucks i'm not doing it". The game also has been out for less than a month and i'd say less than 10% of the playerbase has even made it past Tier 2. Once prices stabalize and other potential "money" making activities are released or not released then i would expect people to make "Best depths to farm for crowns" or "Best areas to farm for /x/ item when it's /x/ theme". You really need drop rates, monster counts, percentages of element type dominance and availability to even start collecting data for definitive places to get items.
As i said before teaching people how to read the gate maps would be much easier so they can do all this themselves at a glance. When they understand that then they can either lookup what monsters are in Scarlet Fortress and from those monsters which ones will spawn in a shock element level and what they drop.
If you wanted you could make a new thread in the wiki section and ask people who regularly edit the wiki to include what types of monsters are found in those places and how many. Because in all honesty new players are not your going to be your desired audience.
The levels don't stay the same. The path down changes quite often and has many variables. It's easier for you to understand how to read the gate map and figure out the best path from there. Which would be easier to make a wiki article about.
