Crit roll table
Crit. Rate and Crit. DMG use the same weights (official disclosure).
| Crit. Rate | Crit. DMG | Exactly this | This or better |
|---|---|---|---|
| 6.3% | 12.6% | 23.33% | 100.00% |
| 6.9% | 13.8% | 23.33% | 76.67% |
| 7.5% | 15.0% | 23.33% | 53.33% |
| 8.1% | 16.2% | 8.00% | 30.00% |
| 8.7% | 17.4% | 8.00% | 22.00% |
| 9.3% | 18.6% | 8.00% | 14.00% |
| 9.9% | 19.8% | 3.00% | 6.00% |
| 10.5% | 21.0% | 3.00% | 3.00% |
This or better: the chance that a crit substat rolls at least this value. A goal such as Crit. Rate ≥ 8.1% uses this column: 30.00%.
Both crits at or above a value
Both crits: 12.82%. Top rolls: × 3.00% × 3.00% = 0.0115%.
| Goal | Chance per echo | Echoes per hit |
|---|---|---|
| Crit. Rate and Crit. DMG, any roll | 12.82% | 1 in 7.80 |
| Crit. Rate ≥ 8.1% and Crit. DMG ≥ 16.2% | 1.15% | 1 in 87 |
| Crit. Rate ≥ 9.3% and Crit. DMG ≥ 18.6% | 0.251% | 1 in 398 |
| Crit. Rate ≥ 10.5% and Crit. DMG ≥ 21.0% | 0.0115% | 1 in 8,667 |

1 Tacet Field run (60 Waveplates): about 24,155 Echo EXP (4.8 Premium Tubes) and 20 Premium Tuners. 240 Waveplates per day.
One run drops tubes and Tuners together, so the scarcer one sets the runs. Echo drops are not counted.
Money: a 60-Waveplate refill costs 60 Astrite (the first 2 each day). 1 pull = 160 Astrite. At the $99.99 Lunite pack, 1 Astrite ≈ $0.0124, 60 Waveplates ≈ $0.74, and 1 pull ≈ $1.98.
Other ways to buy Waveplates: Sage's Solvent Aid, $4.99 for 7 Crystal Solvent, is $0.71 per 60 when the shop offers it. The Lunite Subscription, $4.99 for 3,000 Astrite, is $0.10 per 60, for up to 3,000 Astrite a month.
Shops: a Premium Sealed Tube also sells for 250 Monnaie (Averardo Bank) or 50 Data Sets (Simulation Training Store, 25 max).
