OUTERPLANE: Tyrant Drakhan Dark Weapon 10 Burst Guide

To hit a 63,000 damage burst with Tyrant Drakhan in OUTERPLANE's Dark Weapon Stage 10, you must trigger her Burst Level 3 ultimate while the stage boss is in the Break state and afflicted with Defense Down.

Dark Weapon Stage 10 features high armor and damage reduction that prolong the fight into dangerous counter-mechanics. Bypassing these phases requires tuning Drakhan as an offensive glass cannon, pairing her with dedicated buffers, and timing your party rotation to break the boss right before Drakhan attacks.

Stat Benchmarks and Gear Setup

Reaching the 63k threshold requires prioritizing offensive substats over survivability. Drakhan needs consistent critical scaling and enough defense penetration to cut through the boss's base armor.

Critical Hit Rate (85%–100%): You must cap or near-cap this stat through equipment and team buffs. Missing a critical hit ruins the burst window.
Critical Hit Damage (250%–280%): This is the primary multiplier for scaling her ultimate damage once critical hits are guaranteed.
Defense Penetration: Equip a 2-piece Penetration set. Penetration applies before critical damage multipliers, providing significant scaling against Stage 10 defense values.

Gear Slot / Set	Target Stat	Priority Rationale
4-Piece Set	Critical Damage % or Attack %	Maximizes base damage scaling for her ultimate skill.
2-Piece Set	Defense Penetration	Cuts through the boss's innate armor rating.
Necklace	Critical Hit Damage % Main Stat (50%+)	Supplies the highest single-item critical multiplier.
Ring	Attack % or Penetration Main Stat (40%+)	Raises raw baseline damage prior to critical scaling.
Boots	Speed or Attack % (Speed-Tuned)	Ensures Drakhan acts immediately after buffers and debuffers.

Required Support Buffs and Debuffs

Drakhan cannot reach 63,000 damage without external combat enhancements. Because buffs and debuffs scale multiplicatively, your team must apply the following effects before her attack:

Defense Down (50% Armor Reduction): Essential for lowering the boss's mitigation. Without this debuff, ultimate damage typically tops out near 30k.
Attack Up and Critical Damage Up: Supports such as Valentine or Tamara provide party-wide offensive enhancements and Action Gauge manipulation to align turn order.
Action Point (AP) Generation: You need sufficient AP pooled to cast Drakhan's ultimate at Burst Level 3. Use Chain Attacks and multi-hit basic attacks to generate AP during preliminary turns.

Turn Sequence and Break Execution

Follow this combat sequence to align your buffs with the boss's vulnerability window:

Build AP on Wave 1: Defeat preliminary mobs using basic attacks and low-cost skills. Reserve Drakhan's Burst gauge and high-impact cooldowns for the boss.
Buff the Party: Open the boss encounter by casting Attack Up and Critical Hit enhancements on your speed-tuned supports.
Deplete the Break Gauge: Focus multi-hit skills on the boss to empty the weakness meter and trigger the Break state.
Inflict Defense Down: Apply a 2-turn Defense Down debuff immediately before or as the boss enters Break.
Execute Burst Level 3: Cast Drakhan's ultimate at maximum Burst level while the boss is broken, Defense Down is active, and Drakhan holds offensive buffs.

Manual Play vs. Auto-Farming

This setup is optimized for manual clears and milestone farming where turn timing can be controlled directly.

Running this glass-cannon composition on full auto-play introduces failure points. If an automated run fails to land Defense Down due to boss resistance, or if an ally triggers the Break state prematurely out of turn order, the team lacks the defensive stats to survive a prolonged battle. If you want to adapt this setup for consistent auto-farming, increase Drakhan's Speed stat slightly or swap in an auxiliary unit with consistent Break-gauge reduction to smooth out AI timing errors.
