Some badges have conditional bonus effects that can be activated if you meet the described requirement:

The conditions include:
  • A survivor has a specific trait. Example: +5% if this Survivor has the Defensive Stance trait
  • Your survivor joins a mission team with another survivor of a certain class. Example: +50 when this Survivor is on Missions with a Scout
  • Your survivor joins a mission team with a specific Hero. Example: +10% when this Survivor is on Missions with Maggie.
Note: The second and third conditions above look at the using different combinations of survivors. Since Carol cannot “go on a mission with Carol”, you will want to equip badges that refer to Heroes on survivors who are not the specified Hero.
