Party Composition#
Principles of Party Building#
Baldur’s Gate 3 parties hold a maximum of 4 members — a sensible party composition matters more than any single strong character. The core principle is one front-line tank plus one healer / support plus two damage dealers — though different situations call for different setups.

Synergy Effect |
Notes |
| Shadowheart + Lae’zel |
Bless raises the fighter’s hit rate — the fighter protects the cleric |
The most classic tank + healer pairing |

A perfect control + damage combination |

Front and back line working together — barbarian tank + warlock ranged damage |

Explanation |
| Stability first |
Pick companions with steady damage — do not rely on random factors — avoid crit builds |
| Healing is mandatory |
At least one person knows healing spells — Death Ward is a must — Cure Wounds is the floor |
| Control chains matter |
Hold Person / Fear / Hypnotic Pattern — cut the number of enemy actions — take less damage |
| Insurance |
Everyone carries Invisibility potions + Revivify scrolls — flee on a wipe — protect the save |

Co-op Teamwork Tips#
| Tip |
Explanation |
| Clear division of roles |
Everyone sticks to their own job — do not steal your teammate’s work |
| Communicate before engaging |
Discuss the plan before the fight — who controls, who damages — avoid wasting actions |
| Share resources |
Potions / scrolls are shared between inventories — give them to whoever needs them most |
| Positioning |
Melee stays in front — ranged stays in back — do not block each other’s line |
