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.
Important! If you want to check how well Oku does in the current meta of all heroes in AFK Arena, please check out my current tier list of all heroes here. Oku’s Signature Item
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.. If you want to learn more about my recommended priority how you should invest into Signature Items in AFK Arena, check out my SI Priority Guide here. 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.

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. Engraving
In terms of Engravings, your final goal should be E0.. Do not invest into any engravings here Learn more about my recommended engraving priority here.
