If you want to make Oku perform at peak performance in AFK Arena, you need to run the right built. While many players think simply maxing out will do the trick (well, not too wrong), there are certain sweetspots with Oku that will give a big boost so I have some recommendations below that you will very likely find interesting.
Oku’s Signature Item should be at +20. Not overwhelming but is needed if you want to run him frequently, especially in Faction Tower where he has the most common use..

Furniture Recommendation
Overall it’s recommended to get Oku’s 9/9 furniture set bonus. Oku’s furniture bonus 9/9 with the permanent damage reduction is actually mandatory if you want to run him overall and takes some of his squishy-ness by letting him survive better.

Recommended Artifacts
Waistband of Resilence is the best artifact to run with Oku in most cases, although you can also consider running Lifes Limit or Duras Call as backups, depending on your team setup and what artifact you have available.
