Wiki notes
When bonds matter
Bonds are mainly relevant if you play with the same people, trade items, or want co-op buffs. The page notes that bond type differences currently do not provide actual benefits.
Because leveling is task-driven, treat bonds as a daily routine rather than a one-session grind.
What to do in game
Build bonds with players you actually run dungeons with.
Complete daily bond tasks before pushing long sessions.
Check bond level before planning higher tier trades.
