Survival Strategy Guide
The Future Devil Contract is powerful but risky. Failing a counter results in a massive penalty. Use this calculator to determine if you can survive a failed attempt.
- Always calculate before PvP: Know your "safe HP" threshold.
- Heal Up: If your calculator result shows "LETHAL", use meds or healing abilities immediately.
- Max HP Matters: Increasing your Max HP also increases the damage you take from a failure (since it's percentage-based).
Future Devil FAQ
What is the exact penalty?
The penalty for a failed counter is exactly 30% of your Maximum HP. This is true regardless of your current HP.
Can I die from the penalty?
Yes. If your Current HP is less than or equal to 30% of your Max HP, failing a counter will reduce your health to zero or below, resulting in instant death.
does defense reduce the penalty?
No, the contract penalty is true damage and ignores defense stats. You must have the raw HP to survive it.
