Climax Boost amplifies Crit Rate, Crit Dmg and Evasion

Weakness

Damage highly dependent on Climax Boost uptime

Sunraku is a Melee DPS hero from the Shangri-La Frontier collaboration who brings a unique blend of self-buffs and team support through his Crit Rate amplification. His core mechanic revolves around maintaining the Climax Boost buff, which dramatically increases his damage output by stacking Crit Rate and Crit Damage.

The main appeal of Sunraku lies in his ability to apply Bleed on critical hits while simultaneously boosting the team's Crit Rate. However, his tier placement in C suggests he faces significant competition from higher-tier heroes who either deal more damage or provide stronger utility.

🤔

Should You Use Sunraku?

Sunraku is a solid but situational pick. He works well in teams built around Multi-Dot scaling heroes, where his Bleed application adds value. However, for general content, higher-tier DPS heroes will outperform him.

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.

Why Sunraku Stands Out

Sunraku occupies a niche as a Melee hero who both applies Bleed and provides team-wide Crit Rate amplification. This combination makes him valuable for DoT-focused team compositions, though he requires careful buff management to maintain optimal damage.

Best Game Modes

  • Boss content — Climax Boost provides significant burst during its 10-second window, useful for Hard Boss Challenge phases
  • 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. Crit Damage as a secondary stat amplifies damage during Climax Boost windows. This build works well across Deep Nightmare, Hard Boss Challenge and Tower of Ascension content.

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
