Dr. Ratio is an Imaginary-element character who follows the Path of The Hunt. He is a DPS unit whose playstyle revolves around applying Wiseman’s Folly to a single enemy. This effect is considered a debuff, making him a good fit for the Pioneer Diver of Dead Waters relic set. Wiseman’s Folly enables him to trigger Follow-Up Attacks twice, greatly enhancing his damage output.
In addition, Dr. Ratio can inflict other debuffs on a single enemy to increase his CRIT Rate and CRIT DMG by up to 15% and 30%, respectively.
As a Hunt character, he excels at dealing high damage against boss-type enemies, making him especially effective in single-target encounters.

Izumo is a good set for Dr. Ratio when paired with another Hunt character like March 7th or Moze, as they function more as sub-DPS units.
