The Roster Rule is one of the regulations applied to Duels.

Compared to standard Duels, this regulation places greater importance on predicting which assets your opponent has brought into the Duel.

Roster Rule Features

In Duels where the Roster Rule is applied, you must first register up to 18 asset slots consisting of Heroes and Extensions for use in the Duel.

You may enter even if your total registered assets do not fill all 18 slots; however, you must include at least 3 Heroes.

During that Duel, you may only use the assets you have registered.

Registered assets cannot be changed mid-Duel.

Even if you registered fewer than 18 assets, you cannot add more during the Duel.

Roster Visibility

During a Roster Rule Duel, the assets each user has brought in are initially hidden from other users.

Only assets that have been used in attack or defense during the Duel will be revealed to others as part of your brought-in assets.
