Juzu Bracelet is a common relic: "Regular enemy combats are no longer encountered in ? rooms." It can only drop before the act 3 treasure chest.

What a ? room becomes

Without Juzu, a ? room rolls these base chances:

ResultBase chanceAfter each ? room without it
Fight10%+10%
Merchant3%+3%
Treasure2%+2%
Eventeverything else

The result you get resets to its base chance. The chances reset at the start of each act.

With Juzu, the fight result is removed. Its share goes to events, and the fight chance stops growing:

After several ? rooms in a row

Without Juzu, the fight chance climbs with every ? room that was not a fight:

? rooms in a row without a fightFight chance on the next one
010%
120%
230%
340%
450%

With Juzu that chance stays at 0%, so a path through many ? rooms gives events, Merchants and treasure only.

Other rules for ? rooms

  • A ? room cannot be a Merchant if you just left a Merchant, or if every room after it is a Merchant.
  • On your very first run, the first two ? rooms are always events and the third is always a fight. Juzu does not change this.
  • ? rooms never become elites in a normal run.
