Best Ways to Use Door in Reverse 1999: Skill Breakdown and Build Guide

Door is a unique 2-star Support character in Reverse 1999 with an Intellect affinity, specializing in Reality damage and team support. Although Door's role is unconventional compared to high-rarity damage dealers, his distinctive kit focuses on supporting his team through buffs, shields, and Moxie generation rather than direct damage output.

Skill Breakdown

Door's core skills revolve around providing Reality damage and crucial support buffs:

Deep Vortex: This is a single-target attack that deals significant Reality damage, starting at 200% at level 1 and scaling up to 500% at max level. While effective for damage, its main value lies in Door’s ability to trigger his other skill effects rather than raw damage output.

Converging Mirror: A mass attack that targets two enemies, dealing Reality damage from 150% to 375%. This allows Door to contribute consistent damage against multiple targets while supporting the team.

Inheritance – Modesty: This passive skill is the heart of Door’s utility. Upon Door's death, allies gain +1 Moxie, enabling faster ultimate skill charge. Additionally, when Door enters battle, the team receives an 8% reduction in damage taken, boosting survivability. This combination not only accelerates the team's ability to unleash their ultimates but also provides defensive cover, making Door invaluable in strategic team play.

To The Universe In The Alley (Ultimate): Door’s ultimate instantly buffs all allies with +2 Moxie, grants a shield based on Door’s ATK for added protection, and applies Inspire for 2 rounds (+1 starting Moxie). After this, Door sacrifices himself, which is a strategic trade-off for massively boosting the team's combat capability.

Build and Psychubes

Who to equip and how to build Door is key to maximizing his potential:

Best Psychubes:

The Footloose increases Door's damage when attacking targets above 50% HP, enhancing his offensive contributions.

A Free Heart reduces damage taken when Door’s HP is below 50%, improving his survivability until he uses his ultimate.

Equipment Strategies:

Focus on boosting Door’s ATK stat to strengthen shields and damage from skills. Items that enhance support efficiency, survivability, or Moxie synergy complement his kit well.

Team Synergy and Strategy

Door excels when paired with characters who benefit from fast ultimate cycling and shield support:

Synergy with Necrologist: One of the most effective combos is pairing Door with Necrologist, who can resurrect Door after his ultimate sacrifice, allowing Door to repeatedly boost Moxie and shields for the team. This combo is especially powerful in longer battles or PvP.

Team Composition: Use Door in teams with strong ultimate damage dealers who can take full advantage of the Moxie boosts he provides. His shields also help keep fragile teammates alive during high-damage phases.

Tactical Use: Door’s strength lies beyond just dealing damage. His ultimate and death trigger are tactical tools to accelerate team ultimates and provide shields at critical moments. Timing his ultimate to maximize team buffs is crucial in battles.

Conclusion

Door is a specialist support character who transforms from a seemingly weak 2-star unit into a pivotal team asset through his unique ultimate and passive abilities. Properly equipped and paired with synergistic team members, Door can dramatically influence the pace of battle by enabling rapid ultimate usage and shielding the team from damage. As such, Door offers strategic depth and value far beyond his rarity or raw stats in Reverse 1999.​
