#2-1: Terra's Dawnlight
“
May Terra bestow us the courage to cast our gaze further into the distance.
In Abyss Rejection Deep Dives, the player will start with a lower Light than usual of 70, thus one must pray that their Operators don't get a Rejection as early as the 2nd floor, which can mess things up! To make things worse, the Light loss from clearing an operation after losing Life Point(s) is doubled to 10, forcing the player to be extra careful lest their Light falls low enough to make Rejections occur more often!
Speaking about Rejections, they are also enhanced, which will be explained in the specific strategies below.
Esthesia Lapse
In this Deep Dive, the Rejection is fixed to Neurodegeneration+ where compared to the normal Neurodegeneration, the Freeze duration is doubled, stopping the Operator dead in their tracks for 30 seconds, but to compensate, their ATK and DEF will be tripled whilst the Operator is Frozen by said Rejection, and the player is given Castle's Offspring to increase Operators' defenses after they are deployed long enough. To complete the Mission Objective, the player must make their way into the 5th floor.
Exacerbated Mutation
In this Deep Dive, the Rejection is fixed to Metastatic Aberration+ where compared to the normal Metastatic Aberration, the Operator's HP, ATK, DEF, DP cost, and redeployment time are cut by a sheer 75% but their initial SP is increased by a grand 80, and the player is given Rhodes Island Tactical Transceiver and Four-Leaf Clover Fossil to expand the Rec. Voucher and Collectible options. To complete the Mission Objective, the player must recruit 15 Operators other than the initial three ones.
Adrenaline Rush
In this Deep Dive, the Rejection is fixed to Hemopoetic Inhibition+ where compared to the normal Hemopoetic Inhibition, the HP loss is doubled to a grand 300 HP per second but the Operator's ATK will be increased by 1.2% for every 1% of their missing HP (e.g. the Operator has +60% ATK at 50% HP) to compensate, and the player is given Coin-Operated Toy and Chivalric Commandments - New Edition to increase friendly units' ASPD by 8 for every 5 in their possession! To complete the Mission Objective, the player must obtain 50 other than those given at the start.
Mania
In this Deep Dive, the Rejection is fixed to Concentration Disorder+ which is similar to the normal Concentration Disorder but with the added effect of increasing the Operator's ATK by 2% and reducing their ASPD by 2 every second when their skill is not active, which caps at +60% ATK and -60 ASPD, and will reset after the skill expires, and the player is given Three-Key Contract to give 3 at the start. To complete the Mission Objective, the player must spend 3 .
Heed the Call[]
In Heed the Call Deep Dives, the player will be able to receive Enlightenments even if their Light is below 100 by rolling a 6 or higher (8 or higher at 0 Light) in dice rolls upon entering a new floor, and Enlightenments are enhanced:
Ursus' Warcry becomes Ursus' Warcry+ which lasts for no less than 5 minutes instead of 30 seconds, effectively making it permanent in most operations!
Yan's Viccisitudes become Yan's Viccisitudes+ where the SP generated is doubled.
Columbia's Inspiration becomes Columbia's Inspiration+ which gives a grand 120 Command EXP, enough to bump the Command Level by at least three in one sitting!
Sami's Tenacity becomes Sami's Tenacity+ where the HP regeneration is doubled.
Victoria's Honor becomes Victoria's Honor+ where the dodge proc chance is increased to 55%, slightly better than 12F and Durin's talents combined!
Leithanien's Elegance becomes Leithanien's Elegance+ where the defense buff is increased to 500 DEF and 50 RES, essentially rendering weaker ranged enemies only scratching ranged Operators and allowing them to resist stronger ranged enemies better!
Sargon's Generosity becomes Sargon's Generosity+ which gives no less than four random Collectibles!
Terra's Dawnlight
In this Deep Dive, the player is given Inquisitor's Scripture Cloth which gives 1 dice roll after clearing operations. To complete the Mission Objective, the player must make 7 dice rolls.
Parliament's Messenger
In this Deep Dive, the player will have Victoria's Honor+ at the start and is given Old Steam Armor. To complete the Mission Objective, the player must obtain 30 other than those given at the start.
Empresses' Voice
In this Deep Dive, the player will have Leithanien's Elegance+ and a random Enlightenment at the start, and are given Broken Wand - Arts Weaving and Broken Wand - Malediction which makes Casters more hard-hitting but more squishy (although the Elegance's effects offsets this to a degree). To complete the Mission Objective, the player must obtain 15 Collectibles other than the aforementioned.
Coronation
In this Deep Dive, the player will start with only a singleLife Point but will have four random Enlightenments at the start and are given three "King's" Collectibles to offset that: King's Crown, King's New Lance, and King's Staff, thus so long as the player has only 1 , friendly units will have +150% ATK and +50 ASPD, and generates 1 SP every 2 seconds. To complete the Mission Objective, the player must simply complete the run.
Seize Victory[]
In Seize Victory Deep Dives, Call(s) of We Many have a higher probability to be heard but Temporary Recruitment Operators also have a higher probability to appear.
In this Deep Dive, the player is given Hand of Purification which causes enemies inside the range of Bard Supporters, Phalanx Casters, and Therapist Medics to take Arts damage over time, Nachzehrer's Cane which deals Arts damage to enemies nearby an "overhealed" friendly unit, and White Flower Crown to boost healing received by friendly units. To complete the Mission Objective, the player must enter 4 Emergency Operation nodes.
In this Deep Dive, the player is given Hand of Buckler which causes Abjurer, Decel Binder, and Hexer Supporters to deal Arts damage equal to a portion of the target's HP in each attack as well as Stalwart Aid - Assistance and Stalwart Aid - Diligence which buffs the ATK of friendly units in a Supporter's range and cuts the SP cost of Supporters' skills, respectively. Furthermore, Supporter Rec. Voucher will appear more often than other Rec. Vouchers. To complete the Mission Objective, the player must simply complete the run with at least three Supporters recruited.
