Debuffs

The boss does not only take. Sometimes it leaves something behind.

A debuff is a curse your weekly boss leaves on you — a lingering penalty that follows you for days. Every boss has its own signature debuff (Wanderer's Haze, Leaden Curse, and so on — each boss card on All Bosses shows what it does). An active debuff appears in red on the Legacy tab and on the boss card.

When Debuffs Land

Debuffs are rolled once per night at the 2am reckoning, and the odds depend entirely on your Grace level that day:

Grace LevelDebuff Chance
Blazing0% — untouchable
Burning0% — untouchable
Flickering10%
Forsaken35%

That top half of the table is the real defense: a Burning-or-better day cannot be debuffed at all. Debuffs are how the realm punishes streaks of bad days, not single stumbles.

How Long They Last

Every debuff carries a countdown in days, set by the boss that inflicted it — usually Standard 4 days · Veteran 6 days · Legendary 7 days, though a few bosses break the pattern. The counter ticks down at each 2am run and the debuff expires on its own when it hits zero.

What They Do

Effects vary by boss — each one attacks a different part of your progress. The families you'll see:

The exact effect and numbers for every boss are on its card in All Bosses.

Getting Rid of One

Grace Ward vs. Debuff — know the difference

A Grace Ward absorbs a bad day (a Grace tier drop). It does not block or absorb a debuff — and a grace-attacking debuff applies its effect after the Ward has done its work. Wards protect your Grace; only Boluses, Sites of Grace, and time remove debuffs.
