Teams in Re:BIRTH are five slots, and the difference between a coherent team and five strong solo heroes is enormous. Build in three steps: choose your damage core, add general supports, then graduate to dedicated monotype supports as your roster deepens.
Step 1 - Choose your main damage dealer
- Physical: Lu Bu, Teo, Kyle, Klahan
- Magic: Freyja, Reginleif, Rin, Yeonhee, Sun Wukong
- Death: Kris
Other than Sun Wukong and Kris, you can freely run two damage dealers from the same category - damage lands more frequently, which pushes stages faster.
Step 2 - Add general supports
Rachel, Lina, Alice, Ryan, Evan, Yui, Deo, Elysia, Ace and Vanessa all provide great generic support for adventure pushing. They eventually fall off once you obtain dedicated monotype supports - especially in Nightmare Adventure - and certain stages will also require Immunity heroes slotted in (the Roles & Effects page lists every provider).
Step 3 - Graduate to dedicated supports
- Physical DMG support: Kagura, Karl Heron, Branze & Bransel, Randgrid, Fai, Dellons, Eileene, Gelidus, Guan Yu. Run full Attack-type teams (or at least 3) to feed Lu Bu's and Kyle's passives. Gear: Assassin/Bounty Hunter sets with Crit Rate, Weakness Hit Chance and DMG accessories.
- Magic DMG support: Mercure, Melia, Vanessa, Kyrielle, Orly, Daisy, Xiao Qiao, Juri, O'Mok. Same logic - 3+ Magic types for Freyja's and Reginleif's passives; Melia and Mercure also want multiple Magic allies. Same gear pattern.
- Death support: Mist, Aquila, Rosie, Knox, Alice, Rudy, Nia, Pallanus. Death teams are mostly a Nightmare Adventure tool (only one phase to kill) - gear them with the Spellweaver set and Death accessories to push Death's proc chance.
Type synergy - read this before locking a team
Hero types aren't just cosmetic. The clearest example: Lu Bu's kit requires three or more Attack-type allies - without them his Blessing doesn't activate and the team's Magic Attack takes a massive penalty. Check your carry's conditions before building around them, and lean into type-matched cores when a kit asks for it.
Sample teams (Infinite Tower too)
- ATK team: Randgrid / Lu Bu / Branze & Bransel / Teo / Karl Heron
- Magic team: Mercure / Freyja / O'Mok / Reginleif / Kyrielle
- Universal team: Radgrid / Sun Wukong / Lina / Pallanus / Elysia
- Death team: Pallanus / Mist / Aquila / Kris / Rosie
Swap heroes out for Immunity providers or buff removers when a stage demands it. For 3-star clears you may need a Taunt unit with damage immunity to prevent deaths, and if you have one dominant carry, a solo-backline 1-4 formation protects the rest. Legendary Accessories go on these cores first in late Nightmare stages.
When a fight isn't working
Before leveling further, check three things in order: is your carry's type condition met, is your gear on the right heroes (DPS - Tank - Support), and does the enemy counter your core (a Sun Wukong opposite your Freyja is not a levels problem). Most walls are composition problems wearing a stats costume.
