I think if we were going to do a Crafting/Gathering Dungeon, Some good ideas might be something more "event" oriented and not really a "dungeon crawl" since a dungeon crawl doesn't fit DoL/DoH classes. Since DoH/DoL classes are a little harder to optimize dungeons for (I.E a SMN can replace a MNK or NIN or DRG etc, DD are interchangable, but if we were to do specific crafting, a Goldsmith cant replace a blacksmith if you want a Spinel Ring...), It would be better if the crafted items or gathered items are treated more like the dailies for Beast Tribes, where all crafts can craft them. So with that in mind, heres what I'd propose for some "Crafting Dungeons", and "Gathering Dungeons".
DoH/4 Man Dungeon - Level 20(Sync at 23)- Order Up!
Goal: You're hired to cook for a popular restaurant, its going to be busy and theres going to be a lot of hungry guests. Gather food from the (dispensers) and get crafting!
How it works: There will be multiple guests who want different things, each of them will also have a time limit. Your goal is to get food out to them as fast as possible, if you miss to many orders, you fail and must start over (like wiping to a boss).
**Phase 1: 4 "Waves" of patrons, a couple (2), a small family (4), another Small family (3), and an elderly couple (2). You're have 5 minutes to deliver the required items to each person, and they come in at staggered times (I.E they don't all come in at once). This phase will last 15 minutes with the groups coming in at 0, 4, 8, 10. The final couple will request High Quality food only.
**Phase2: 5 "waves" of patrons, a large family (6), a group of Scholars (4), a couple (2), and a lone woman (1). The group of Scholars will request you deliver their requests in alphabetical order, while the lone women will request high quality food. This wave will last a total of 20 minutes (or when all food is delivered)
**Phase3: 1 "Wave" of patrons, a group of 16 sailors. Will request at least half their food be of high quality, and will want them in under 10 minutes (think of this as the final boss).
This is however... not to say... dungeon crawling wouldn't work for DoL/DoH... I give you.
DoH/DoL - 4 man, 2 DoL/2DoH. - Rescue Operations. (Level 35)
Description: There's been a cave in reported in (Copperbell Mines<?>) and we're looking for some capable crafters and gatheres to help with rescue operations. We'll provide as much support as we can but the mine is rich with minerals, so you should be able to mine and build anything you need to progress.
How it works: You'll essentially be two teams working as one. There will be enemies throughout the dungeon, but can be dispatched in different ways using the DoL's Sneaking abilities. The goal will be to get to the trapped miners and escort them to safety. A rough breakdown of how the Dungeon could work.
You are given a small cache of supplies, Each DoH will receive including 3 Bombs, 3 Blasting caps, 3 Pinches of Bomb Ash, and 3 Bomb Shells. This gives you enough supplies for 12 bombs... each DoL will receive 3 Potions that recover 300 GP each with 60 second cool down, 3 "dungeon unique" items that increase mining success by 20%, and 1 "Ironworks Sledgehammers" which is a one time use item that deals heavy damage to one obstacle (ike a DoL Limit Break). Entering the dungeon there will be a rock formation in front of you consisting of 3 targetable points, as well as several normal "mining spots" with materials that can be crafted into explosives to clear the way quicker. A strategy could be one man mining the rocks while another hits the points to supply the crafters with bombs. When mining the Formation, it will work differently than a normal point, in this case the goal is to destroy it... Mining these points will open a screen that will have 3 mining options:
"Loose pebbles": High Success rate (80~+) - Deals 200 HP to rock formation. (Critical Mining will deal double)
"wiggling Rocks": Medium Success rate (50~+) - Deals 500 HP to rock formation. (Critical Mining will deal double)
"Rough Boulders": Low success rate (20%~) - Deals 1000 HP to the rock formation. (Critical Mining will deal double)
The boulders will have around 5,000HP. Failure on wiggling rocks and rough boulders has a small chance to deal damage to the player and lower their GP by a small amount, which makes them more risky. Bombs can be used to deal 1000 HP to any rock formation, but you have a limited supply. After clearing the first rock formation, you will enter an area that has several mining points and a few bomb enemies. Each mining point will have a random material that you can use to craft more of the unique DoH/L items you get at the beginning. One of the mining points (at random) will have a mining option of "Avalanche!", It will have a medium success rate, and if successful it will collapse the room above the bombs destroying them, and providing the DoH with more bomb ash for bombs. If failed, it will move to another random mining point in the room. However, if it is not successfully gotten within 2 minutes of entering the room, the bombs will self destruct. The mining points in the room will provide the DoH with supplies to craft for the DoL as well as themselves, making the dungeons much easier to do.
Near the end of that room will be another a cluster of 3 rock formations, same formula as above, once destroyed there will be a "Thick rock formation" behind it, which will be much tougher to destroy, having 10,000 HP. This formation also has a chance on failure to spawn an enemy (weak enough for a DoH/DoL to kill without much trouble, can also be killed with a bomb). After the formation is destroyed, you will enter a large circular room, in the middle will be a group of goblins miners trapped by some rocks, with a Gigas attacking them. This is the first "Boss" of the dungeon. Your goal is to clear the rocks and help defeat the Golem. there will be 10 rock formations blocking in the goblins/golem, the goblins can be defeated if you take too long, and if defeated the boss ends in failure and you have to retry.
There will be mining points that appear and disappear in timed intervals, these will provide you with supplies to craft bombs. Each formation has 3,000HP, bombs can be used to speed up the process. The "Ironworks Sledgehammer" will deal 4,000 damage to any formation, making it useful, but crafting more isn't guarunteed, and each DoL only has one. You can also use bombs, and while you can craft more, they might be needed to defeat the boss... Choose wisely! Once the formations are destroyed, you will be able to target the Gigas. the Gigas has 30,000~HP(possibly more) but there are multiple ways to damage it, and multiple ways to tackle the fight.
In this room the mining points that appears will allow you to mine "Odd Liquid", "Smelly Liquid", "Sweet Liquid", as well as normal ores for bomb shells. the Odd Liquid can be crafted into a potion will apply a buff on any goblins in its AoE that increases their attack speed and defense, the Smelly Liquid can be used to craft an item that will apply a "Vulnerability Up" effect on the Gigas for 20 seconds, doubling its damage taken, and the "Sweet Liquid" can be used to craft a potion that cures the goblins in the AoE circle. Each item can be high qualitied and doubles their effects. So the DoL/DoH will have to work together for best result.
The DoH can also contribute when not mining materials, by mining "Boulders" in the area which will have the option of mining
"Small Rock" - ~90% - Can be thrown at the Gigas. Deals 300 Damage.
"Medium Rock" - ~70% - Can be thrown at the Gigas. Deals 800 Damage.
"Large Rock" - ~50% - Can be thrown at the Gigas. Deals 1500 Damage.
Works like a normal node, after 4 mining attempts the boulder will vanish (respawning 30 seconds later). The Gigas will defeat the goblins within about ~10 minutes of starting the fight. The Gigas will also not target the players directly (though he can use AoEs...).
Once you free the Goblin Miners, they provide you with a few small supplies. 2 Bombs, 2 Shells, and 2 Bomb Ash, as well as 2 Treasure Coffers. One containing a slew of Materials (Crafting materials of appropriate level range), and the second one A Green(Or Blue at higher level) unique DoL/DoH armor piece.
Okay, the Rescue Operations can obviously be continued, but I'm drained ATM on ideas and im really tired... But you get the idea of it. DoL gather materials, DoH crafts items. Can even include mechanics like crafting a key to move on, or crafting a pick axe/hoe/scythe required to move an obstacle, etc.
Exp be will granted for Mining/Crafting as normal to each individual miner/crafter... Group exp will come from bosses and obstacles. individual Exp inside the dungeon from mining and crafted items will be higher than normal crafting/mining for your level (like how mobs in dungeon give more exp than mobs in the open world). A level 50 dungeon could theoretically be implemented that grants tokens similar to Soldiery, used to purchase I.lv 55/60 Crafting gear, and they could also have level 50 dungeons that reward hard to get synth mats (in NQ or HQ, maybe making a place where you can more commonly get hard to find HQ synth mats).
The task of the DoL will be more of a "DoT" effect on walls and such, as well as providing valuable materials to crafters. The crafters will be tasked with providing goods to the group (GP Potions, mining success items, explosives to speed things up). Each role will be important. I'm kinda happy with this idea... If i could submit it to the Devs I would, might provide them with a bit of inspiration on how a DoH/DoL dungeon could work.
Maybe one of you nice community reps could do it for me :3
Edited: A little bit of derp.
