"Those betrayed hearts sank into the depths, slowly forgotten in the ever-lengthening corridors of time."
- Abnormality Log

Old Faith and Promise (T-09-97) is a Old Faith and Promise (1) ZAYIN Abnormality tool that takes the form of 2 marble lizard or chameleon-like creatures that change color depending on the current interaction. Both are divided into jigsaw-piece likes section, with 4 "puzzle pieces" connecting to form a single creature, including their tails. Their heads are not styled like puzzle pieces despite being connected the body. Each head has a single rhombus shaped eye with a slit pupil. The lizards are on opposite sides of a bubble-like orb, one on top connected to the ceiling of the containment chamber with one rope on each other its three segments, while the other holds itself upside down to the bottom of the bubble.

Old Faith and Promise's ability consists of sending an employee, along with a small amount of Old Faith and Promise (2) energy as the cost, to bet their E.G.O. Weapon, which will be placed in a small orb that will enter to the Abnormality's orb. Once inside, the object will start to shake side to side while making resonant noises. There are two possible outcomes at the end of this process:

  • Good Result (Great probability of success): The Abnormality Tool turns golden and shine, as the employee stare in awe and burst into happiness, cheering as it waits for the tool to return its E.G.O. Weapon back. The weapon will get boosted damage by a percentage, increasing the Max. and Min. Damage Power of the weapon by an average amount (Small base damage will get a low increase of damage and big base damage will get a higher boost).
  • Bad Result (Small probability of failure): The Abnormality Tool turns pitch black, returning back to its spot as the employee gets on their knees, while having a painful expression of regret. The employee will get back up and get out of the containment. The E.G.O. Weapon will be lost and can be recovered only by buying another from their respective Abnormalities. Resetting the day or restarting from the Memory Imprint day will not return the lost weapon.

The process can't start without Old Faith and Promise (3) Energy and the power boost will only last for the day. One E.G.O. Weapon can be boosted up to four times per day, and further boosts will have no additional effect. The Abnormality doesn't work when sending an agent wielding a basic Baton Stick Weapon.

Log and Method[]

Interaction Amount



1 Use

"A mysterious marble which hangs in the Containment Unit."

"Utilize the Abnormality to fortify an E.G.O Weapon. This will consume a small amount of the facility’s currently collected energy."

3 Uses

"We know of an ancient practice; the countless promises that were made, and the unending faith placed in them."

"The fortified weapon will have higher Attack Power."

3 Uses

"However, all that they yielded was only hollowness and betrayal."

"However, there is a possibility of losing the E.G.O during the fortification process."

5 Uses

"Those betrayed hearts sank into the depths, slowly forgotten in the ever-lengthening corridors of time."

"The fortified weapon will lose the Abnormality’s power after the day has passed."

7 Uses

"If you make an attempt with an austere heart devoid of desire or expectation, however, you may receive an unexpected reward."


  • This Abnormality is the first one that can change the stats of an E.G.O. Equipment directly, by boosting the damage of a weapon, as well the first one to destroy E.G.O. Equipment.
  • Binah's Sephirah Upgrade doesn't prevent the destruction of the E.G.O., as the employee doesn't die.
  • The name of this Abnormality might be inspired from an incident named "Kiri's Belief and Promise", which caused chaos to the Korean PC RPG game "Dungeon and Fighter" (Dungeon Fighter Online). An equipment reinforcement system in the game resulted in one of two outcomes: success, increasing the stats of the equipment; or failure, reducing the stats by several upgrade stages or even destroying the equipment if the upgrade level was high enough. "Kiri's Promise" was a consumable item released at one point in the game which prevented equipment upgrade failure from taking any effect on the item being upgraded (ie, it would neither be destroyed nor lose any stats).
  • Classified as 'Trauma', this Abnormality attempts to show through its logs how those who expected great rewards, were often left with betrayed hearts; while those who tried without high expectations would receive unexpected rewards. This Abnormality represents this clearly, as repeated uses might leave the player with vastly upgraded equipment, or the loss of their E.G.O.
  • This is 1 of 2 Abnormalities that hang from the ceiling. The other is Spider Bud.


  • This tool saves the entire E.G.O "inventory" when destroying an E.G.O weapon, allowing one to save or permanently destroy E.G.O without having to memory repository.[needs reference]
