A simple and obvious scheme with the shortest path containing 4 rooms, 3 different paths are available. The first “layer” consists of 3 plain rooms, the second one - of 3 treasure rooms with one “appendix” with treasure.
The fifth troop has been added to Emperinazar (and Khaziel, of course) - Kobold Thief (Epic Striker). It cat fit some teams based on gold, but hardly useful within the delve.
The layout looks very similar to the regular delve in the Hall of Guardians. One path to the finish with 3 rooms and 6 dead-ended rooms. Only 4 treasure rooms here, but you can choose the visiting order.
Another troop has been added here (and to Karakoth as well): Dark Mason (Epic Striker). Not very useful globally, maybe within pure faction team only.
I hope I’m remembering correctly. I was surprised on my first run that the right V was the only non-treasure room. (I had the gnome room in the centre).
This scheme is almost the same as the regular delve’s one, just without passes between central rooms. So the full pass from S to F takes 5 rooms. You can choose one of two available passes. There are only 3 treasure rooms in this delve, without occasional treasures.
The fifth troop has been added to this delve: Black Ooze (Epic Assassin). It looks dangerous against one-colored teams due to its devouring spell. Very possibly it can simplify passing the delve with pure faction team.
It’s the first delve where we go from the right to the left. Despite it, the scheme is not so interesting as the regular delve here. The only pass from S to F is short - just 3 rooms, through plain V room. And all other rooms are treasures and do not stand on your way to the finish. Looks somewhat like inverted Eldrazhor scheme.
The fifth troop has been added to this delve: Hellclaw Shadowpriest (Epic Striker). Poorly consistent with other faction troops: it conjures Darkstorm (only Purple gems, instead of Hellstorm - Purple and Red gems, which fits the faction), and its spell depends on Purple gems only. Not a useful troop really.
A very simple scheme, it may remind of Fang Moor or the Black Heart: just one path from S to F having 5 rooms, and some sideways. As far as I could investigate, central rooms IV, II and V are plain, and peripheral rooms are treasures (4 of them).
The fifth troop has been added to this faction: Bloodflower Duchess (Epic Support). It can be useful in pure faction pass, but hardly anywhere else.
A fairly straightforward scheme, where you see only one path from start to finish 4 rooms long. Like many deep delves, it has 4 treasure rooms and 3 plain. No occasional treasures as far as I could investigate.
The fifth troop has been added to this faction: Polymetis (Epic Defender). It can help with pure faction pass, and also maybe in some soul teams.
Another simple scheme with only one way to the finish. What is more interesting here - there are 2 occasional treasure rooms, which we seldom see in deep delves. And 3 firm treasures also (but it’s obviously less than in the regular Wyrmrun delve - 6 treasure rooms and only one plain V).
The fifth troop has been added to the faction: Drake Eggs (Epic Warmaster). A strong addition, which can help either in pure faction pass or in some battles outside delves.
A straightforward scheme with “S - IV - III - II - F” rooms for the main pass and 4 treasure rooms in two blind ends. No occasional treasure rooms as far as I could explore.
The fifth troop has been added to this faction: Skulker (Epic Striker). It belongs to “Goblin/Rogue” class, but it’s the first goblin without an extra turn. Kinda weird after all goblins and kobolds (goblin/naga) in the game. Looks not very promising, you may get it to develop the kingdom of Blackhawk.
A very simple scheme with 2 paths: two plain V rooms or 5 treasure rooms. Almost the same as the regular delve.
The fifth troop has been added to the faction: Lightborn Enchantress (Epic Generator). Her spell is good for some Ultra-Rare troop, but an Epic?.. I doubt it’s useful. But it’s yet another troop for Nexus.
An interesting scheme, for instance, unlike the regular delve scheme. You can choose a path with 3 rooms (S - V - F), with 4 rooms (S - IV - IV - F) or more. You can see 3 plain rooms here and 4 treasure rooms.
The fifth troop has been added to the faction: Fire Ettin (Epic Warrior). It looks better than Fire Scorpion due to its generator subrole - exploding 4 Burning gems. Can be useful in pure faction passes.
This scheme can remind you of the Warrens deep scheme: 2 long ways to the finish, 5 rooms in each, and a side room. We can see 3 treasures here, other 4 rooms (II, III, IV and V) are plain as far as I could investigate.
The fifth troop has been added to the faction: Alabaster Knight (Epic Warrrior). Another warrior that gains attack and armor with its spell. Can be useful in delves with pure faction team. And another troop for the developing kingdom of Hellcrag.
Another deep delve with occasional treasures - two rooms II. Nothing “cunning” about it, just 2 ways to the finish: either S - III - IV - F or S - II - V - F. No deep dead-ends, luckily.
The fifth troop has been added to the faction: Court Witch (Epic Warlock). Can be useful within pure faction run, but hardly anywhere else.
Not a very puzzling scheme: straight pass from start to finish, 4 rooms in total, and 4 blind-ends with treasures. As far as I could investigate rooms IV and V on the main path are plain, they cannot be treasures. It reminds about other deep delves: one in Mirrored Halls, or one in Duergaroth.
The fifth troop has been added to the faction (and to Mydnight): Dark Acrobat (Epic Striker) - with true pointed Fey ears (while Strongman and Ringmaster have non-pointed ears). May help in passing delves by a pure faction team, but hardly anywhere else.
All factions have deep schemes and 5 troops for now. What can we see?
The best regular delve for collecting treasures - Wyrmrun. It has 6 treasure rooms, maximum for regular delves. The second best regular delve for the same - City of Thieves.
For quick pass (just completing “Deep Delver” task) there are many good regular delves: Mirrored Halls, Crypt Keepers, Hall of Guardians, All-Seeing Eye, Eldrazhor - just to name some.
The best deep delve for hunting Gnomes - Duergaroth. Firstly because of the shortest path to possible Treasure room (with a Gnome), secondly because of an effective delve team: High King Irongut / Thrall / Zuul’Goth / Orbweaver + Doomed Baton under Hall of Guardians banner (or you may take any hero class, Orbweaver is just the most convenient). the second best deep delve for hunting Gnomes - Depths of Sin, another good scheme for hunting, but less effective team: Amarok / Thrall / Zuul’Goth / Orbweaver + Doomed Baton under Hall of Guardians banner (Amarok is not so reliable as HKI; if you know a better team for Red/Purple delves, please post it).
Some numbers finishing the deep delves:
they took 3 years and 4 months to add to every faction: from 27 May 2022 to 26 September 2025;
the shortest time span between regular and deep delves - Nightmare Circus (obviously): regular delve added on 19 January 2024, deep delve - on 26 September 2025, 1 year and 8 months;
the longest time span between regular and deep delves - Sunken Fleet: regular added on 17 May 2019, deep - on 30 June 2023, 4 years and 1 month (but several factions have close periods - about 4 years between regular and deep delves);
factions started on 11 September 2018 - we can celebrate 7 years with them!
About new troops (5th for each faction): can’t remember very useful ones, but I can easily name the worst: Skulker (a Goblin without an extra turn) and Hellclaw Shadowpriest (inconsistent with its faction), they are useless even for pure faction passes.
We already know that the second cycle of Friday Faction Assaults is planned from October 2025: Gloom Ocularen (Ultra-Rare Warlock) will appear in All-Seeing Eye according to current spoilers. But if there will not be more delve schemes, this thread will stay without updates. You can always find it using forum search.
Would nominate Rattigar Cutpurse from Dark Pits over those 2 for worst. Skulker/Hellclaw Shadowpriest are near the top for actually badly designed troops, but have very small niche uses in their pure faction. Cutpurse fails on synergy (gold related troop in a non-gold faction) and fails on damage compared to Hexrat, leading to 0 use cases. Stealthy on a useless troop actively puts your other troops in even more danger than normal.
Big fan of Thrall (purple) + Tesla (red). so…
Essence of Evil (Orbweaver or Geomancer depending player preference or luck)
Thrall (can be swapped in position with EoE depending on player preference)
Tesla
Zuul’Goth or The Archduke
