The Best Way to Build Dr. Ratio Character

Best Dr. Ratio DPS Build

Dr. Ratio’s optimal setup is as clear as day! It’s all about capitalizing on that Wastelander of Banditry Desert set to boost his critical rate and damage when the enemy is debuffed or imprisoned. With the 4-piece set effect activates reliably, maximizing his damage output, thanks to having a consistent debuffer on the team, it’s a recipe for success.

Furthermore, the Inert Salsotto artifact complements Dr. Ratio’s kit by enhancing his Ultimate and Follow-up Attack Damage when his CRIT Rate exceeds 50%. Achieving this threshold is straightforward, especially considering his unlockable Traces, ensuring that he can capitalize on the artifact’s bonuses effectively.

This free-to-play team adopts a classic Hypercarry configuration, with Dr. Ratio serving as the primary Damage Per Second (DPS) dealer. Yukong plays a crucial role in boosting Dr. Ratio’s Critical stats, enhancing his damage potential. Meanwhile, Asta contributes by buffing Dr. Ratio’s Speed (SPD) and has the capability to inflict Burn on enemies, further augmenting the team’s offensive capabilities.

  3. Debuffer: Silver Wolf
  4. Healer: Huohuo

Topaz proves to be an excellent complement to Dr. Ratio, offering additional Damage (DMG) and amplifying his Follow-up Attack Damage. On the other hand, Silver Wolf significantly boosts Dr. Ratio’s chances of executing Follow-up attacks by inflicting numerous debuffs on enemies. This synergy ensures that Dr. Ratio’s potential is fully realized, resulting in devastating damage output.
