To build Maxwell (Professor) effectively in OUTERPLANE, configure him as a pure burst mage focused on Critical Hit Damage, Attack, and Critical Hit Rate. Maxwell functions primarily as an area-of-effect (AoE) cleaver capable of dismantling high-defense frontlines by bypassing enemy armor. Because his burst ceiling relies entirely on accumulating Calculation stacks and pooling Action Points (AP), your build and team lineup must guarantee turn setup before he fires his ultimate.

Best Gear Sets and Stat Benchmarks

Equip Maxwell with a four-piece Critical Damage Set combined with a two-piece Critical Hit Rate or Penetration Set. Because his ultimate shreds enemy armor through built-in mechanics, investing heavily in raw Attack and Critical Damage provides greater damage scaling than stacking multiple penetration gear pieces.

Aim for 85% Critical Hit Rate unbuffed, or 70% if you consistently run him alongside critical chance buffers. Avoid allocating substat rolls into Effect Resistance or defensive health and defense stats, as unoptimized damage rolls prevent him from securing one-shot clears against tanky defenders.

Calculation Stacks and Combat Execution

Maxwell's primary offensive engine is his Calculation mechanic. His passive grants Calculation stacks whenever allies attack debuffed enemies or when Maxwell takes an action. Each stack raises his Attack and Critical Hit Damage.

At maximum stacks, his ultimate, Singularity Explosion, applies extensive Defense Penetration that can ignore up to 100% of enemy armor when cast at higher Burst tiers. As a Dark-element mage, his attacks bypass elemental glancing penalties against Earth, Fire, and Water defenders, giving him consistent neutral damage across diverse matchups.

To execute his rotation:

  1. Ensure your team applies multi-target debuffs to prime enemy targets.
  2. Trigger allied attacks to feed AP and cap Maxwell's Calculation stacks.
  3. Unleash Burst Level 2 or Level 3 Singularity Explosion to clear the field.

Team Compositions and Turn Order

Maxwell cannot operate effectively in slow stall teams or without combat acceleration. He requires dedicated allies to supply buffs, apply debuffs, and feed Action Points before his turn arrives.

Structure your team rotation using the following roles:

  • Turn Pushers and Critical Buffers (Valentine or Tamara): Provide Critical Hit Chance and Critical Hit Damage increases while manipulating the Action Gauge. Their opening attacks trigger dual attacks that immediately generate Calculation stacks.
  • AoE Debuffers (Dolly): Applies team-wide debuffs such as Silence and Accuracy Down. These mass debuffs suppress enemy threats and ensure every subsequent allied attack increments Maxwell's passive.
  • AP Batteries and Secondary Attackers (Noa or Hanbyul Lee): Apply single-target pressure to threatening units and generate the 50 to 100 AP required for Maxwell's higher Burst tiers.
  • Defensive Cleanse Support (Tio or Faenan): Grants Immunity and cleanses crowd control when facing disruptive enemy debuffers.

Skill Upgrades and Transcendence

Focus your skill resources to maximize burst scaling:

  1. Skill 3 (Singularity Explosion): Maximize first to increase base damage multipliers and Defense Penetration scaling.
  2. Skill 2 (Passive): Upgrade second to boost the passive Attack and Critical Damage gained per Calculation stack.
  3. Skill 1: Leave this basic attack for last, as it contributes minimally to your cleave rotation.

For transcendence, stop at 5 stars for standard play. A 5-star Maxwell provides sufficient baseline stats to execute cleave strategies in Arena and clear multi-wave PvE encounters, such as upper Skyward Tower floors. Reserve limited Dark memory resources rather than pursuing 6-star transcendence, as the extra base stats are not required for his core armor-piercing mechanic to function.
