![[Blood Key] Blood Proof-02 Battle Guide [NUCarnival]](https://yurucani.com/en/wp-content/uploads/eye-en-nucarnival-blood-key-stage-02.png)
This is a guide for the high-difficulty battle “Blood Proof-02” in the Blood Key event.
Stage Guide
Party Formation
| Taunt | No need |
| Remove guard stance | No need |
| Recommended CD | CD4 or Lower |
The stage includes significant HP recovery by the enemy, and forced defeat occurs at certain HP thresholds. If you’re losing to these conditions, using characters with healing reduction skills can help.
Characters with CD3 can use their special skill on the 4th turn. This allows them to stack the buff “Self Attack +14%” early.
If your party’s damage is insufficient, prioritize adding CD3 characters.
Battle Tips
| AUTO Battle | ー |
| Skills | should be saved, except for healers who can use their skills at any time. |
You will lose the battle if any of the following occur:
- Failing to reduce the enemy’s HP below 50% by Turn 11.
- Failing to reduce the enemy’s HP below 25% by Turn 15.
- Failing to defeat the enemy by Turn 19.
Every time the enemy attacks, their HP is restored.
- Your character takes 40% of their max HP as fixed damage.
- Your character gains +14% Attack (stackable up to 4 times).
You will take counter damage even if the skill has no attack effect (e.g., healer specials).
