Verdict

Situational

Strength

Active damage + Crit support

Weakness

Dependency on specific buff uptime

Sunraku is a Melee DPS hero from the Shangri-La Frontier collaboration. He relies on his Climax Boost mechanic for damage and team-wide Crit Rate amplification, offering a specialized role in DoT-focused compositions.

While his potential in specific team comps is notable, he is generally outperformed by modern DPS heroes, making him a niche choice that requires careful management to shine.

Sunraku in hero interface

Strengths

Climax Boost amplifier — grants +20% Crit Rate, +20% final Crit Damage and +50% final Evasion for 10 seconds, significantly boosting damage output during the buff window.

Team Crit Rate support — Keen Attack Lv. 5 provides +20% Crit Rate to all allies for 2 seconds on every successful critical hit, enabling faster skill rotations for the team.

Bleed application — inflicts Bleed on critical hit targets, contributing to Multi-Dot damage and enabling synergies with heroes that scale off DoT types.

Weaknesses

Buff Boost lower than standard — the percentage value of the buffs is well below that of the newly released heroes..

Collaboration Hero — Can only be obtained during limited periods.

Recommended Synergies

Frontman Dellons Ranged Multi-Dot DPS who gains +30% Crit Damage per DoT type. Sunraku's Bleed application feeds into Dellons's 7-stack scaling.

Supreme Justice Juri Ranged Multi-Dot DPS who scales +20% Crit Damage per DoT type. Sunraku's Bleed contributes to her 3-stack requirement alongside her team Attack buffs.

Big Game Hunter Trude Trude deals significantly more damage when Bleed is active on the target, which Sunraku reliably provides.

Best Game Modes

Boss content — Climax Boost provides significant burst during its 10-second window, useful for adventure Boss.
Farm content — consistent crits and team Crit Rate buff help maintain damage throughput

Build & Optimization

Prioritize Critical Hit Rate to ensure consistent Bleed application and to trigger Keen Attack buffs for the team. Even if you build him with Crit, do not expect to play Sunraku in Deep Nightmare content; he is simply too weak.

Investment Advice

Early game

Low priority — other heroes provide better value

Mid game

Medium priority if running DoT compositions

Late game

Situational — valuable in DoT-focused teams only

FAQ

Is Sunraku worth pulling?

As a collaboration hero, he is worth considering if you run DoT-based team compositions. For general use, higher-tier heroes offer better overall performance.

Is it worth building Sunraku with an Evasion-focused build?

No, in the current meta, a 50% Evasion boost is simply too low. With that stat threshold, he will almost never successfully evade incoming enemy attacks.

Can Sunraku be used as a primary Lead DPS against Guild Bosses?

No, even in the early game, he is no longer viable for this mode. His damage multipliers are simply too low to compete with modern DPS units.
