** Nyarlathotep's Skill Crawling Chaos and Cthulhu's Call of R'lyeh inflict the status change Gloom on all enemies at the start of the first turn and at the start of each enemy turn, respectively (it's not coded as an ailment, so it cannot be resisted or dispelled). By itself, it decreases hit rate, evasion rate, crit rate, and chance to inflict ailments by 20%. Crawling Chaos will additionally increase all Magic attack received and decrease all Magic attack inflicted by 25%, and Call of R'lyeh will increase the damage dealt by Cthulhu to Gloomy enemies by 30%.
** Lanling Wang's Flying High inflicts the Zenith effect on all of his teammates, increasing their Phys hit rate, evasion rate, crit rate, and chance to inflict status ailments by 20% while decreasing the damage dealt by critical hits and ailment chance by 20%, and his Mask of Veiled Beauty increases Phys attack by 25% and 30% to crit rate as long as he's alive for any teammates with Zenith. If any effect inflicting Gloom triggers against any demons with Zenith or viceversa, both ailments will cancel themselves out instead. Fariedone's Hero of Prophecy will inflict Zenith on all teammates at the start of his own turn, and all demons on his side will receive an additional 25% boost to their Phys attack and 30% to their hit rate.

* DeaderThanDead: There are some attacks (Skull Knight's Sword of Actuation, Lilith A's Temptation, Tzitzimitl's Disastrous Eclipse, Flauros Hallel's Baptisma, Elizabeth's Ark, Echidna's Freezing Gale, Astaroth's Lord Astaroth and Nyarlathotep's Otherworldly Force) that disable resurrection for any enemy killed by those attacks. Berserker Guts' Berserker Armor passive used to inflict this on himself, since it inflicted a massive 40% HP penalty at the end of the enemy's turn - which ignored Endure skills, but he's later buffed to take only 30% damage and without revival block. However, all these anti-revival attacks lose out to Maria, whose unique skill specifically removes revival block.

* CameBackWrong: Revival skills are one of the only ways to guarantee full HP restoration, via Samarecarm, Recarmdra, or Xi Wangmu's Peach of Immortality passive. Persephone's Fruit of the Dead passive, however, will make every revived demon come back with only 1 HP; Rumor Reiko Kashima's passive You're Next will transform any demon who she kills by a single-target skill into a Lv. 1 Reiko Kashima if revived.

* DeaderThanDead: There are some attacks (Skull Knight's Sword of Actuation, Lilith A's Temptation, Tzitzimitl's Disastrous Eclipse, Flauros Hallel's Baptisma, Elizabeth's Ark and Echidna's Freezing Gale) that disable resurrection for any enemy killed by those attacks. Berserker Guts' Berserker Armor passive used to inflict this on himself, since it inflicted a massive 40% HP penalty at the end of the enemy's turn - which ignored Endure skills, but he's later buffed to take only 30% damage and without revival block. However, all these anti-revival attacks lose out to Maria, whose unique skill specifically removes revival block.

** There are some demons who reward you for fielding multiple demons of the same race in a team. Examples are the Heralds Gabriel, Raphael and Uriel, who each use an offensive ability with an added debuff when used in a team with two other Heralds, and Tyrant Lucifuge, whose Hell's Ministry passive and panel each allow for all Tyrants' Almighty skills to be used for 1 MP less, intended to work with Lucifer to allow him to spam his Morning Star.

* {{Plaguemaster}}: Nergal's Plague of Babylon removes all enemy Barriers and inflicts Weak on them, all but guaranteeing any ailment that comes next will stick. Angra Mainyu's 16 Scourges slams the enemy with ''every single ailment in the game'' plus an unstoppable 25% HP hit.

* SecretArt: All 5★ demons[[note]]except Ananta[[/note]], some 4★ demons and a rare few lower grade ones have one or two skills that are unique to them and cannot be transferred. More unusually, all members of the Wood race possess the Power of Life Skill.

* DifficultButAwesome: Multi-Fusion can be a tricky task, as Multi-Fusion only accepts Common Archetype demons[[note]]with the single exception of Beelzebub (97), which requires the gacha-exclusive Beelzebub (Human)[[/note]], meaning gacha demons aren't usable and you'll probably have to execute long chains of various Fusions to gather your components. However, Multi-Fusion demons typically have useful, unique attributes that can't be found on other demons, like Hare of Inaba, who has a Passive that nulls Dark Zone effects and greatly reduces Poison Trap damage while in the Aura Gate.

** There are several demons with a passive skill that nulls all ailments (Kinmamon, Daisojou, Mahamayuri and Maria), and additional skills that confer immunity to one ailment, or two at most [[note]]Null Bind/Weak, Null Mute/Curse and Null Charm/Poison are the only skills that can stop two ailments; the first is found only on Adramelech, the second on Nyarlathotep, and the third on Cthulhu.[[/note]]. Some demons also gain ailment immunity from panels, such as Griffith and Beelzebub (97) who get Null Charm, Null Mute and Null Bind from their Panel 2, or the Moirae sisters whose panels confer various ailment immunities to Lady/Femme demons, including themselves.

** Lanling Wang's Flying High inflicts the Zenith effect on all of his teammates, increasing their Phys hit rate, evasion rate, crit rate, and chance to inflict status ailments by 20% while decreasing the damage dealt by critical hits and ailment chance by 20%, and his Mask of Veiled Beauty increases Phys attack by 25% and 30% to crit rate as long as he's alive for any teammates with Zenith. If any effect inflicting Gloom triggers against any demons with Zenith or viceversa, both ailments will cancel themselves out instead.

** Kartikeya and Sraosha are the third and seventh fastest demons[[note]]Kartikeya's Skanda skill gives additional 20 AGI when maxed, allowing him to outspeed even Hresvelgr[[/note]], further augmented by innate Speedster for both, and their second Panels increase their base speed by 30%, which can be further increased with Agility Amp III or Epitome of Swiftness. However, they're on the low, low end of HP, making it easy to destroy them if the enemy team survives.

** Your demons' level cap is 50. Not only reaching this cap can be quite easy since the game can sometimes be generous with Exp, you will start running into enemies who break that level cap long before you max out your demons with brands, spiritizations and mitamas.

** Several demons can revive dead teammates if they survive an enemy turn. Usually there is some condition or limit: Nebiros can revive every turn but need to have at least one enemy cursed, while Echidna and Maria can only revive a number of times per battle.

** In most of the game modes, you can encounter enemies whose levels are much higher than the level caps would usually allow. The final enemy of each Brands of Sin quest, for example, is at Level ''65'', when your own demons max out at Level 50 (and that's for 6★ demons). Hollow World enemies escalate this by slowly going all the way to level 99 the deeper you go, and Tokyo Abyss goes to town by introducing enemies with ''triple-digit levels'' by the time you reach around 30F.

* DeathOrGloryAttack: Physical ''attacks'' (not to be confused with physical ''attribute'') can critical or miss, unlike magical attacks which never miss but can't critical. Scoring any critical will give you bonus turns even if the enemy has no weakness, but if your multi-hit attack misses just ''once'', no amount of criticals can recover that lost turn. All Phys attribute skills are physical attacks, but some physical attacks may have other attributes, such as Cu Chulainn A's Barbed Spear, which is Force attribute.

** Slowly but surely played straight with demons. Higher grade demons have unique skills that are often better versions of skills owned by lesser demons, and 5★ demons have better spiritization bonuses than 4★ demons. Still, some lower grade demons may have more useful stats, skills, resistances or stat infusion limit and thus still see play.

* {{Roguelike}}: Tokyo Abyss in Alter World is a seasonal dungeon where your MC dives deep without your usual collection of demons. Instead, every time you start a new abyss run, you only bring your swords and shield and must recruit demons and level up along the way.

* SkillSlotSystem: Each demon has six slots for skills and passives. Three of them are fixed skills that the demon always knows. One of them is an Awakening skill, which can change depending on the demon's Archetype. The last two are slots that can be used to inherit other skills. 3-Star demons and above, when pulled from the gacha, will receive an additional move in one of the free slots.

** Bind prevents the target from dodging and acting, instantly skipping their turn
** Charm causes the target to do actions beneficial to the enemy, like attacking their allies or healing the enemies.
** Mute prevents the target from using any skills, limiting them to only basic attacks or pass. Despite being less potent than Bind and Charm, Mute usually lasts longer.

* ComboPlatterPowers: Some rare skills are essentially a combination of several lesser skills crammed into a single slot. Some of them are transferable, such as Fire Survivor skill (combines Fire Boost's +15% fire damage and Endure's LastChanceHitPoint), while the rest are unique to extremely high-level demons, and non-transferable, such as Ardha's Sahasrara (Infinite Chakra's extra MP regeneration, Great Aim's accuracy bonus, Assassin/Serial Killer's bonus to all damage, and a healing bonus almost as good as Recovery Amp, all in a single Skill)

* ManipulativeBastard: [[spoiler:Lucifuge tricks Tokisada into amassing enormous amounts of power by presenting himself as a "voice from the heavens", and cheats him out of it all at the end of the ''God's Tragic Hero'' event.]]

** In most of the game modes, you can encounter enemies whose levels are much higher than the level caps would usually allow. The final enemy of each Brands of Sin quest, for example, is at Level ''65'', when your own demons max out at Level 50 (and that's for 6★ demons). Hollow World enemies escalate this by slowly going all the way to level 99 the deeper you go, and Tokyo Abyss goes to town by introducing enemies with ''triple-digit levels'' by the time you reach midway out of 60 floors.

* TookALevelInBadass: At the game's launch, Tyrant Beelzebub was a fairly underwhelming demon at level 69, and his SecretArt Gluttony quickly became obsolete due to his lackluster Magic stat, inability to Pierce, and no defensive ability. Cue the ''The Fly King Reborn'' event, in which he suckers another fragment of his power, the benevolent storm god Baal, into allowing him to fuse with his human form (Beelzebub (Human)), creating a ''much'' higher-leveled and far stronger Tyrant Beelzebub.

** Almighty attacks are also not as strong as they usually are, even if some of them are still useful. The main reason is that elemental attacks with pierce are abundant in this game, and they have better amount of supports via other skills[[note]]To give you an idea, whereas other attributes have all manners of Boost, Amp, Survivor, Prana, Enchancement etc skills to support them (most of which increase by 15% in addition to some other bonuses if any, while Amp gives 25% bonus) and can be obtained from various sources, Almighty only has Boost, Survivor and Debuff, which are currently only present in Demiurge, Beelzebub (Human) and the time-limited Elizabeth, all of them in their Aragami Archetype[[/note]] or Aura Gate 2's Berserk mechanic, which can boost all attributes except Almighty.

* GradualGrinder: The Hallel demons' main ability, though they have strong main attacks. As they use their SecretArt and charge its Boost Levels, they gain more and more positive effects at the start of their turn or add penalties to all enemies.

* MindRape: A mysterious letter draws Megakin, Vagit, Kazufumi and the MC into Cthulhu's dream, keeping them in a state of sleep with constant nightmares. While in the real world they stay asleep for about two days, the group is forced to descend into the dream until they realize they're actually in a vision of R'lyeh. While everyone makes it out after the final door opens, the MC was the closest and the one who got the most exposure to whatever was on the other side. They awaken to convulsions and incomprehensible groaning, and are taken to a hospital for a month. In the end, they escape to the beach, and while they get picked up, their last line is Cthulhu's SignatureLine, as they give the ocean a last longing look.
