Maniac Trait Overview
Maniac is a Mythic trait in Grand Blue with an S-tier ranking and a listed 0.15% chance. Its power depends on your current HP: it weakens your damage while you are healthy, then becomes much stronger once you drop below half health.
| Trait | Tier | Rarity | Chance |
|---|---|---|---|
| Maniac | S | Mythic | 0.15% |
Maniac Effect
Maniac is built around the 50% HP threshold.
| HP Condition | Effect |
|---|---|
| Above 50% HP | -10% DMG |
| Below 50% HP | +25% DMG and -15% DMG taken |
In practice, Maniac is a high-risk trait: you lose damage while above 50% HP, but gain both offensive and defensive value once you fall below 50% HP. That makes it more appealing for players who can survive and keep fighting while damaged rather than players who want consistent damage at full or high health.
Is Maniac Good?
Maniac is listed as an S-tier trait, so it belongs among the stronger trait options for players comparing Grand Blue best traits. Its main drawback is that the trait does not give constant upside: the damage penalty above 50% HP means you only unlock its best value after taking enough damage.
Choose Maniac if you want a trait that rewards aggressive, low-HP fighting. Avoid relying on it if your build or playstyle depends on staying safely above half health.
