NTE Team Comps

The 6 Esper elements sit on a wheel, and only elements next to each other on that wheel trigger a Duo reaction when paired. Chain two Duo reactions from the same side of the wheel and they escalate into a Trio, which hits noticeably harder.

• Pick a Duo or Trio first, then fill the team with characters whose elements match that lane — this beats picking your four strongest characters and hoping their elements happen to line up.
• A team that keeps one lane intact usually deals more sustained damage than a team of four powerful characters spread across unrelated elements, because reaction damage compounds on top of normal attacks instead of just adding to them.
• The fourth slot is where most teams flex — reserve it to solve a specific problem (survivability, energy refill, crowd control) rather than filling it with whichever high-tier character is left over.

Every character belongs to one of five Arc-compatibility classes (labeled ONE through FIVE), which only decides which Arc weapons they can equip.

• Nothing about team building checks this class — a lane built around three different elements routinely mixes three or four different classes with zero restriction.
• Where class actually matters is gearing day: once a team is set by element and role, go check each member's class separately to know which Arc pool to pull or craft from.
• Don't let a class mismatch talk you out of an otherwise perfect reaction lane — it only affects which weapon shelf you shop from, never who's allowed to stand next to whom.

A four-person team still needs someone dealing damage, someone sustaining that damage, and someone keeping the team alive, on top of whatever reaction lane it's built around.

• Main DPS anchors the team and decides which lane the other three build around.
• Sub-DPS adds a second damage source, often the character whose element completes the Duo or Trio with the Main DPS.
• Support buffs damage, extends reaction uptime, or refills the resource the Main DPS needs to keep attacking.
• Healer (or a Support that doubles as one) keeps the team alive in longer fights — skip this only if the content is short enough that survival was never in question.

Only once these four slots are covered by characters that also share a workable element lane does it make sense to reach for a second, more advanced reaction — trying to run two lanes with four characters usually means neither lane is complete.

The Esper Wheel produces a fixed set of reactions, not an open-ended list — knowing the count helps you recognize one when a skill description names it.

• There are 9 named reactions total: 6 Duo reactions from adjacent-element pairs, 2 Trio reactions from chaining two Duos on the same side of the wheel, plus the Blossom mechanic's own Vita Bud/Pistil interaction, which runs on separate rules from the other 8.
• Nova and Scorch are two of those Duo reaction names — and they're not purely a team-building concept. Certain Module suits (gear sets) key their own set bonus directly to participating in a Nova or Scorch reaction, meaning a well-built reaction lane and a well-chosen gear suit can reinforce the exact same trigger instead of being two unrelated decisions.
• Practical takeaway: when picking gear for a team already built around a specific Duo or Trio lane, check whether any available suit's bonus explicitly names that same reaction — that's a stronger pick than a suit chosen purely for raw stats.

Put Rules One through Three together into an order you can actually follow, rather than juggling all three at once.

• Step 1: Look at your strongest character and note their element — this becomes the anchor for whichever lane you build.
• Step 2: Find one adjacent-wheel element among your other characters to complete a Duo; a Trio (chaining a second Duo from the same side) can wait until later.
• Step 3: Assign Main DPS to whichever of those two hits hardest, and Sub-DPS to the other — this pair is now your reaction lane, locked in.
• Step 4: Fill the third slot with a Support that extends the lane (buffs damage, refills energy, or keeps the reaction active longer), picked without regard to Arc class.
• Step 5: Fill the fourth slot with a Healer, unless the specific content you're clearing is short enough that survival was never a real risk — in that case a second damage-focused Support is fine instead.

Only after this four-slot team is running smoothly is it worth reaching for a second lane or a Trio upgrade — treat that as a refinement, not a prerequisite to starting.
