Understand Good Night and Sleep Well
Useful when…
- A Nihility wearer dealing damage to targets with several debuffs.
- A DoT build that can maintain debuffs on its targets.
How do the stacks work?
At S1, each debuff on the target increases the wearer's DMG dealt by 12%, up to three stacks; S5 raises that per-stack increase to 24%. The description says the effect also applies to DoT. The condition is the target's debuffs, so the benefit can vary between enemies and as debuffs change.
When does it fit?
Consider it when the wearer can regularly attack debuffed targets and make use of a broad damage increase that includes DoT. Along the Passing Shore instead applies Mirage Fizzle when the wearer hits an enemy, increasing damage against affected targets and adding an Ultimate damage increase. Before the Tutorial Mission Starts provides Effect Hit Rate and restores Energy when attacking DEF-reduced enemies. Those effects have distinct conditions; neither is a direct substitute for Good Night and Sleep Well's per-debuff scaling.
How should I improve it?
Promotion is its separate six-stage level track. Superimposition improves the increase per debuff from S1 through S5, but requires a copy of this Light Cone for each example step. Because the number of stacks is capped at three, extra debuffs beyond that cap do not add further stacks.
Limitations and tradeoffs
- Its damage benefit depends on debuffs being present on the enemy being attacked.
- The effect caps at three stacks, even if the target has more debuffs.
Common mistakes to avoid
- Counting more than three debuffs as additional stacks.
- Assuming debuffs on one enemy increase damage against a different target.
