Part 4 is about the Lineup.
The lineup can deploy up to 5 Heroes, so you only need to focus on training 5 Heroes.
You will get a Party Effect when there are Heroes with the same attributes in your lineup.
When all 5 Heroes have the same attribute, the Party Effect bonus will be maximized.
We recommend players to deploy 5 heroes of the same attribute in the lineup to get the max Party Effect bonus.
