Princess Connect Re:Dive guide to the clan battle support unit system
Clan Battle is one of Princess Connect! Re:Dive’s most coordinated modes, and the support unit system can make a major difference when a roster is missing a key character. A well-chosen borrowed unit may provide the damage, healing, or utility needed to complete a team and reach a better score.
The system is simple to use, but effective support management requires planning. Players need to understand how units are registered, when borrowing is most valuable, and how support choices fit the current boss rotation and team strategy.
This guide explains the core mechanics, practical selection methods, and communication habits that help a clan get more value from its shared roster.
How support units work
Clan members can register selected characters as support units for other players to borrow. These characters are separate from the units in the borrower’s own roster, allowing a player to fill an important gap without permanently changing their party.
The exact menu names, limits, and borrowing costs can vary between versions and updates. Check the in-game Clan Battle screen for the current rules, especially at the beginning of a new season or after a major balance change.
A support character generally occupies one party slot, so the borrower must build the remaining team around it. This makes role balance important: a powerful attacker is less useful if the party cannot supply enough TP, defense reduction, healing, or survivability.
Setting up useful clan support
When registering a unit, prioritize characters that are difficult for other members to replace. A specialized armor shredder, TP battery, magic support, or high-performing damage dealer is often more valuable than a commonly owned generalist.
Level, rank, equipment, skills, and unique equipment can all affect performance. A support unit with an unsuitable rank or incomplete upgrades may produce a lower score than a slightly less fashionable character with a better build.
Keep the registered roster aligned with the current bosses. A character that excels against a single-target armored boss may be unnecessary during a magic-resistant encounter. Updating support choices throughout the event helps the entire clan respond to changing team compositions.
Choosing a borrowed character
Start with the target boss and the role your team lacks. If your own roster already covers defense reduction and TP generation, borrowing another support may add less value than renting the encounter’s strongest damage dealer.
Borrowed units are especially useful for adapting to a specific damage cycle. A character may enable a full auto team, stabilize a manual loop, or replace a limited unit needed for a popular three-minute rotation. Review the skill timing before committing to a team.
Players should also consider whether the support unit fits their available equipment and party speed. A character that acts too quickly or slowly can disrupt a carefully timed Union Burst sequence, particularly in manual strategies.
Comparing support choices
The best option depends on the boss, team objective, and player experience. The following comparison offers a practical starting point rather than a fixed ranking.
| Support choice | Best use | Main advantage | Common limitation |
|---|---|---|---|
| High-damage attacker | Finishing a short burst rotation | Raises peak damage quickly | May need strict timing or buffs |
| Defense debuffer | Physical or magical damage teams | Improves the whole party’s output | Can be redundant with owned units |
| TP or skill support | Manual and semi-auto teams | Enables earlier Union Bursts | May contribute little direct damage |
| Tank or defensive unit | Survival-focused teams | Prevents failed attempts | Usually lowers maximum score |
| Healer or sustain unit | Long fights and progression | Keeps the team stable | Less useful when the boss is easily controlled |
Clan members should label or describe support choices clearly when possible. Notes such as “physical defense shred,” “magic burst,” or “safe progression unit” help others select a character without testing every option.
Using support efficiently during Clan Battle
Borrow support for the attempts where it creates a meaningful improvement. If a team already clears comfortably, save the strongest support for a boss that blocks progress or for a high-value score attempt.
Coordinate before the battle begins. Clan chat can identify which units are in demand, who is testing a new composition, and whether a registered character should be swapped for another role. This prevents several players from preparing the same niche option while a crucial support remains unavailable.
External pages can also be useful for checking team ideas, but inspect them carefully. A mixed-content site may place unrelated material, such as medical treatment information, beside game videos or guides; rely on clearly identified game resources and avoid entering account details on unfamiliar pages.
Avoiding common support mistakes
One frequent mistake is borrowing a high-damage character without checking whether the rest of the party can protect it. A fragile attacker may fail before its second Union Burst if the team lacks healing, barriers, or sufficient control.
Another error is copying a support-based composition without matching its timing. Clan Battle guides often assume particular ranks, equipment levels, speed settings, or manual inputs. If those conditions differ, adjust the team rather than forcing an unreliable script.
Use these habits to improve support results:
- Register fully upgraded units that answer the current boss lineup.
- Borrow a role that solves a specific team weakness.
- Check rank, equipment, skills, and timing before starting an attempt.
- Tell clan members which support units are being tested or requested.
- Replace outdated supports as the Clan Battle rotation changes.
Support units work best as a shared planning tool rather than an emergency substitute. Review the boss mechanics, coordinate with your clan, and update your registered characters throughout the event so every member has a better chance to build reliable, high-scoring teams.
