What Are Binding Vows?
Binding Vows are permanent, randomized trait modifiers applied to individual units. Accessed exclusively through the Casino zone, they add mathematical buffs (and sometimes debuffs) to your unit's base stats. The system is inspired by the Binding Vows concept from Jujutsu Kaisen.
Core Scrolls
Apply a completely random foundational trait to a unit that currently has no Binding Vow. Used for initial vow application.
Course Crystals
Reroll an existing Binding Vow. The current trait is permanently discarded — there is no way to undo a reroll. Acquired from the Casino store using raid currencies.
Vow Modifier Hierarchy
| Rank | Vow Name | Effect | Drop Weight | Notes |
|---|---|---|---|---|
| 1 | Honored One | +35% All Stats | ~0.8% | Absolute apex trait. On S-Tier units, creates a mathematical anomaly in DPS calculations. |
| 2 | Rapid Might | Reduced SPA | ~5% | Increases raw attack frequency without altering base damage. Massive DPS gain. |
| 3 | Heavy Restriction | +50% DMG, -30% Range | ~5% | High-risk: massive damage but severe range penalty. Best on units placed at choke points. |
| 4 | Restriction | +25% DMG, -15% Range | ~8% | Moderate risk-reward. Viable on most A-tier and S-tier units. |
| 5 | Power 2 | +10% DMG | ~12% | Safe, reliable boost. No downsides. |
| 6 | Power 1 | +5% DMG | ~22% | Entry-level vow. Better than nothing, worth keeping until you can afford rerolls. |
| 7 | Efficiency | -15% Deploy/Upgrade Cost | ~12% | Enables earlier grid placement. Highly coveted for economy-focused strategies. |
| 8 | Fortune Caster 1 & 2 | Behavioral Utility | ~15% | Tied to non-damage performance metrics. Situational value. |
Critical Reroll Strategy
🚨 Never reroll on B-Tier or lower units. Course Crystals are extremely scarce. Spending them on Choso, Panda, Inumaki, or Nanami is a severe and potentially account-crippling misallocation. Reserve all vow investments for fully Ascended Mythic units exclusively.
💡 Use the Binding Vow Calculator before spending any Course Crystals. The calculator uses hypergeometric probability to tell you exactly how many crystals you need for a 90% chance of hitting your target vow, and whether the ROI is positive or negative.
Casino Zone Mechanics
The Casino is a permanently available cooperative environment. It serves as the sole source of Course Crystals and Core Scrolls, linking directly to the Binding Vows progression system.
Casino Raid Meta
Single-target DPS units face total operational failure due to extreme enemy density. The meta strictly demands spammable, piercing units like Hanami to establish interlocking damage fields. Never solo-queue without a fully maxed, Ascended roster.
Optimal Casino Strategy
Pair Hanami (piercing AoE for wave control) with Awaken Yuji (focused boss DPS) using Discord matchmaking. Farm Course Crystals efficiently using the Economy Forecaster to plan your runs.
