Proud mode: picking the right Trio C

Two trios that work great can still produce a poorly optimized third match. This guide explains why, and how to check it before you play.

Proud mode in a nutshell

In Proud mode, your 6-character team is played as two trios: Trio A and Trio B. On a tie, a third match decides the winner. It is played with a Trio C built from your two trios: 2 characters from one and 1 from the other.

That deciding match is the tricky one: it rarely gets as much preparation as the first two.

Why Trio C loses bonuses

Two mechanics depend on who fights with whom. When you mix your trios, they change:

1. Equipment conditions are counted within the trio

A piece of equipment that says “if at least 3 fighters from the same saga are in the team” is active in a trio built entirely around that saga. In a Trio C that keeps only 2 of those characters, the count drops to 2 and the effect switches off. “Per member” bonuses shrink the same way when Trio C has fewer tag carriers.

The opposite also happens: a character coming from the other trio can bring the missing tag and activate an effect.

2. The Leader privilege follows the Leader’s battle trio

The Leader’s Z Ability applies unconditionally to their two trio teammates. If the Leader doesn’t play Trio C, or plays it with different partners, some characters lose those Z Ability lines — or gain them. Other characters’ Z Abilities keep applying to the whole team under their usual conditions.

Picking your Trio C in DBL Optimizer

  1. Switch to Proud mode with the floating switch at the bottom of the screen.
  2. Under each character, click the “TRIO C” box. The tool enforces the rule: you can’t pick a 3rd character from a trio that already has 2.
  3. As soon as 3 characters are selected, the Trio C analysis appears. “Reset” clears the selection.

Reading the Trio C analysis

Total bonus — the sum of every stat gain for the 3 characters in Trio C, with the difference from their original trios (for example “+1,286% · −36%”).

One card per character — their total, Z Ability share and equipment share in Trio C, each with its difference. Z Abilities and equipment multiply each other, so the total difference can exceed the sum of the other two.

What changes in Trio C — the exact list of affected effects, losses in red first, gains in green after:

Best possible Trio C — the tool tests every allowed combination and shows the one with the highest total bonus, with a button to use it.

Tips for a strong Trio C

  1. Keep tag-sharing pairs together. They are the ones carrying equipment conditions.
  2. Prefer low-threshold equipment (“at least 2”) on characters likely to play Trio C: it stays active more often.
  3. Think about the Leader. If they play Trio C, make sure both partners benefit from the privilege; if they don’t, look at the Z Ability lines the analysis reports as lost.
  4. Use the suggestion as a starting point. The total bonus adds up every stat; it ignores kits, cards and your opponent. When totals are close, trust your game experience.
