 A member of DOKI Entertainment, a popular idol with a lively and cheerful personality that is loved by many. However, her background is a mystery, and no one can uncover her past.

In this guide, we will break down DokiDoki’s Skills, how to face this encounter, as well as recommending what we would consider an ideal progression team to help you along the way.

DokiDoki is one of the most unique and challenging boss fights in Threshold—not because she fights you directly, but because she summons waves of enemies to do the job for her. This is a two-stage battle focused entirely around enemy wave management, damage reduction, and mutation mechanics that can spiral out of control if not handled quickly. The first wave features some familiar faces in Blitz Striker Andrew and Unyielding Aegis Andrew, who are accompanied by two security guards. The second wave is full of Meltdown Monsters. But what’s the catch? These summoned enemies all benefit from 50% damage reduction via the Crazed Gathering passive, which can only be removed temporarily by applying control effects like Freeze, Taunt, or Slumber. This sets up the fight as a high-speed race against time, where burst damage and control timing matter more than ever before.

The boss’s core mechanic, Spotlight Focus, marks one unit at a time. If the marked unit is still alive when she casts it again, they mutate into a Meltdown Monster. If they’re already mutated, they instead gain a stack of Frenzy, which boosts their ATK by 100% per stack, up to 10 stacks. This can get out of hand quickly if you don’t kill the marked units fast. The real danger, though, is that mutated enemies also gain powerful new kits, including stuns, AoEs, DEF Down, and Max HP reduction. If you don’t remove them fast enough—or worse, if they stack Frenzy—you’ll be overrun.

To beat this fight consistently, your team should focus on three things:

1. Staggered control to remove damage reduction across both enemy waves.
2. Strong AoE burst to kill adds before they can mutate.
3. Debuff support and strike prep control to keep the tempo in your favor.

Control is non-negotiable—bring two control units and make sure one of them holds their opening skill for Stage 2. Excellent options include Kraken (Freeze), Rin (Taunt), or Kazuyo (Slumber). Rin also brings shields and DEF Up, but keep in mind she is Reason affinity, so she’ll take 100% increased damage at higher difficulties. For AoE nukes, Massiah is a top-tier pick due to his invulnerability, while Lian is a strong early-game option (just avoid her later if difficulty scaling punishes Reason units). Tiamat and Lilith offer both damage and additional control, making them versatile alternatives.

Rounding out your team, you’ll want a debuffer like RC-77 (ATK Down, DEF Down, Strike Prep Down, and Stun) or Kloss (DEF Down, Speed Down, DMG Taken Up). These Swiss-army-knife units help smooth the entire encounter. For support, Chiaki the Echo, DokiDoki, or Lily offer Strike Prep boost, ATK Up, and Speed control, giving your nukers and control units more frequent uptime. If you need healing, Lingluo or Dorothy work well to stabilize between waves.

Sample Comp (Inferno-Ready):

• Kraken (Control – Freeze)
• Rin (Control + Taunt Tank)
• RC-77 (Debuff & Support)
• Massiah (AoE Nuker with Self-Invulnerability)
• Chiaki the Echo (ATK Buff + Strike Prep Boost)

Strategy Summary:

• Stage 1: Open with your first control to remove DR, apply DEF Down, and nuke hard.
• Stage 2: Use your second control to strip DR again, then repeat the burst cycle.
• Don’t waste both control skills at once—stagger them for better coverage.
• Kill marked units quickly to prevent mutations and stop Frenzy stacks before they start.

DokiDoki’s fight is all about sequencing, planning, and efficient damage, not brute force. If you’re struggling, review your team’s Strike Prep, control cooldowns, and ensure you have the right affinity mix to avoid being countered. Done right, this is one of the most satisfying fights in the game.
