Aura Gate is an area that features a randomly generated dungeon with 50 floors. It's open 0~55 minutes every hour and randomized the floors during the 5 minutes that it isn't available. Action power is consumed while inside Aura Gate, which restores at 1 per minute.
Each floor is traditional dungeon crawling with random encounters. A boss is at the end of every floor, and you can return back to any of the floors you’ve cleared every time you enter.
When the time that Aura Gate is open for is over, it will forcibly kick you out if you were exploring.
If you are in a battle, it will not end your battle but wait until the end of the battle.
If you were in a boss battle and defeated the boss, that will still be saved even after you are kicked out of Aura Gate.
The main loot in Aura Gate is Magnetite, 3~4★ Demon Talk, and 6★ Brands, which are found at the highest floors.
Hence, the main goal should to be climb as far as you can, and that’s by seeking out the boss of every new floor.
Floor 46~50 is the best floor to farm Magnetite. To farm Magnetite, you should seek out the MAG chest on every floor and move onto the next.
Earlier versions of the game had an exploitable bug that caused the MAG chest to refresh when taking a break and re-entering AG, resetting the chances of a jackpot/dud by generating a new chest. As of 2021, the chests are global for each floor, so taking a break doesn't reset them anymore.

There are a couple gimmicks in Aura Gate indicated by the tile
Gimmick
Description
Damage Tile
Take damage and lower HP of your party demons every time you step on this tile.
Dark Zone Tile
Consume a lot of action points. Hides the Minimap.
Magnetite Chest
If a jackpot is pulled, you get the amount specified. If you pull a dud, you lose 10% of your max steps. Otherwise you gain a handful of magnetite determined by floor.
Fountain
Restores 50 action points and your party’s HP to full. Usable only once per Aura Gate exploration.
Moon
The moon changes phase every 10 minutes. During the full moon or new moon, the amount of magnetite and experience acquired inside will increase.
Random Item
You can acquire some magnetite or action points or an item.
Gatekeeper
Powerful demon appearing on the floor for all players. Receive a reward according to the ranking of damage dealt at the end.
Gravestone
Appears when another player is defeated. If you choose to battle, you'll battle with the defeated party (this won't affect your main party at all). If you win, you get fame, magnetite, and a demon's soul
Chaos Knight
If you succeed in the picking the right card, the number of random items encountered on this floor will increase for all players, and HP + Steps will be restored to full. If you fail, you’ll take damage or all random items on the floor will become 1 in quantity for all players. There is no indicator for when the White Rider will appear, it’s completely random.
To deal with the gimmicks, a sub party like below is recommended:
Demons with Speedster are optimal, as going second has the cost of the time it takes for the enemy to complete their turn.
You may still use a turn 2 team in Aura Gate, as long as you bring a Makaraka Shift if your weaknesses aren't covered, and Intimidating Stance; you will require decent healing to keep your party sustained, and Zhong Kui with a physical All Targets attack is extremely helpful for clearing encounters quickly and in one turn (though not necessary).
There are only a few random encounters with Pierce; namely Jack Frost, Pyro Jack and Shadow. Jack Frost and Pyro Jack only appear on 41-45F while Shadow does appear past there and has access to Mudo and Mazio. However, with one Intimidating Stance, the Shadows will use Tarukaja, Rakunda and Mazio twice (they may behave differently with a Zio weakness!), so as long as you can kill the encounter in one turn, you can sustain that level of damage.
Barriers are not necessary, but will pretty much ensure a reset is necessary on Lilim encounters unless you have a means to counter ailments otherwise.
Auto-buffs are also very valuable in Aura Gate encounters.
Speedster Options
Fenrir (Purple) - has Speedster + Auto-Taruka. Auto-Taruka is near necessary for clearing encounters in one turn.
Sleipnir - has Speedster + Mahamaon. One of the most-reliable AG sweepers with a powerful Mahamaon and Speedster.
Kama - has Speedster (better transferred to another demon though)
Slow Team Options
Fenrir - Comes with Auto-Taruka. Any color works, although Fenrir isn't going to be doing much unless he has skill transfers, and any color but Purple is suboptimal. A Purple Fenrir does just fine in a slow team; he can run Rakunda to raise your damage further and Makarakarn to cover your team's weaknesses if you can't survive. Consider him if you don't have Zhong Kui.
Zhong Kui (Purple) - Comes with Auto-Taruka, the most valuable buff in Aura Gate by far. Comes with Intimidating Stance, which neuters the Shadow encounter. Highest STR stat in the game, absolutely shreds Aura Gate with All Targets (AoE) attacks, though he may not need it if your AoE damage is good. By far the best slow team option for Aura Gate; every team should have him ideally. A right-arm brand with accuracy as the main stat is greatly recommended for consistency.
Baihu (Purple) - Budget Intimidating Stance option. Two Intimidating Stances will completely neuter many of these encounters and make them quite easy to deal with, or you can use him as your Intimidating Stance. Has Zionga and Elec Boost, so he can contribute to clears pretty well with Mazio.
Beelzebub (Purple) - Has Makara Shift, Mazionga for the several Zio-weak enemies and sustain through Gluttony, making Single Target healing more viable.
Prometheus - Has Makaraka Shift and good All Targets magic damage. Wouldn't be the best farmer without skill transfers. Purple preferred.
Dantalian (Purple) - Has Makaraka Shift and innate Makarakarn as well. Can be used to cover your weaknesses consistently, since most encounters in Aura Gate do not have Pierce.
Azrael (Purple) - Pretty much a worse Dantalian with Tetrakarn instead. Can be helpful if your team is weaker on the physical defense side.
Apis - Budget Makaraka Shift option that also has Tarukaja. Consider him if you're not running Zhong Kui, though you better have some good damage. Teal greatly preferred, though ultimately not necessary.
Tam Lin (Purple) - Comes with Tetraka Shift and Dark Sword. Can consistently disable threats to your composition or the more annoying casters around. Does okay damage, but he would mostly be a fix for a team that is wiping to physical attacks. If you are not covering your weaknesses, replacing Makaraka Shift with Tetraka Shift is a bad idea; if you are covering your weaknesses, then you don't need Makaraka Shift.
Gucumatz (Purple) - Comes with Tetraka Shift. A much more ideal option than Tam Lin. Auto-Tarunda will ensure you can survive and may help with your sustain if your healing isn't up to par.
Sphinx (Yellow) - Comes with Tetraka Shift. Has Mediarahan, the strongest All Targets healing skill in the game, so he can make up for some pretty squishy people.
Sarasvati (Yellow) - No overt synergy with slow teams other than she is kind of slow. Has Mediarama. Barrier and Silent Prayer have a lot of problems, but if she goes first in your team you can run her to counter Lilim.
Feng Huang (Teal) - Comes with Auto-Tarunda and Mediarama. Your best budget option for a healer that can sustain your team.
Pazuzu - Any color is fine, but an Aura Gate team benefits most from Yellow as Pazuzu really wants Samrecarm and it saves the SP of transferring it; other colors can be better if you're willing to invest such as Purple and Teal . Clear can also work if you're just trying to save costs as he is the cheapest 4★ Mediarama option that way. Pazuzu is bulky and good for bossing; he doesn't heal as much as the other 4★ options but works just fine.
This section drops 6★ Brands. Recommended Battle Speed is going to be around 18,400+.
Don't bother farming this set of floors, just move onto the next set at F46~50 by boss rushing (closing app/retreating on every encounter up to the boss).
Recommended Magic Atk: 900+ on Sleipnir/Horus/Shadow
Give Sleipnir Bufu/Bufula if you want to deal with Lilim or Mazio for better coverage. Give your fastest member Ward brands if you cannot kill Lilim on the first turn. This makes her waste three press turns trying to charm your fastest demon. If Fenrir gets Magic Atk on his brands, you can try Mazan instead of Rakunda.
Tarunda is your best friend, make sure to have it up against the boss at all times.
To skip fights, force close the app after you get into a battle and when you re-enter, you'll be at the same tile without an encounter.
Use the fodder party strategy if your party battle speed isn't up to par - switch out your main party with your sub party before you enter the boss battle, and let it wipe for your main party to come in and deal with the fight for real. It's recommended to run Forneus or other stat debuffers like Yellow Illuyanka with Acid Breath, Cerberus with War Cry etc to make the fight easier once your main party enters in. If your demons die instantly in the sub party, run a spare Feng Huang just for Auto-Tarunda.
Abuse Makarakarn and leave the sub mobs alive if they use magic. They will waste the boss's turns (only for Floors 31~40).
Use Chalk Eater to keep up -kaja buffs on your party if you can consistently hit weak points. Otherwise, use Templar Dragon.
Don't be afraid to swap out party members, like removing Ose against Girimehkala on F41.

4★ White Rider, 5★ Alice. You can instantly kill Asherah at the start of the fight, making it much easier.
Kinmamon for barrier/status removal - when Boss 1 dies, Boss 3 will use Mashibabooon (Bind) until success, and you can loop it by using the item that removes all status ailments or by transferring Meparaladi (Bind cleanse) on Kinmamon and using that.
Sarasvati (Yellow) or Sphinx (Yellow) for barrier/status removal and healing - By using Barrier on your demon that goes first, these demons allow you to use Amrita Shower to counter Alice's Mashibabooon spam. If your demon that goes first has Meparaladi, so much the better. Note both these demons have a Dark weakness, so Mag Reflector/Makarakarn is really recommended!
Then do either of the two: kill Alice, or leave Alice alive while attacking Metatron. You'll still be clearing Bind with Kinmamon when Alice uses Mashibabooon.
Make sure to keep uptime on Tarunda, as the enemies hit very hard.
Bring Templar Dragon as your Liberator to make your items use ½ Press Turn.
Magnetite, 3~4★ Demon Talk, and 6★ Brands, which are found at the highest floors.
Hare of Inaba with Dmg Panel V I & Dmg Panel V II, or 
Ame no Uzume with no transfers required.
