If you want to make Raku 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 Raku that will give a big boost so I have some recommendations below that you will very likely find interesting.
Raku’s Signature Item should be at +30. Raku’s Signature Item is simply insane. The haste reduction keeps basically active on the enemies and the extra damage burst is also super strong.. 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 Raku’s 9/9 furniture set bonus. Raku’s 3/9 will apply a buff to himself if hitting enemies he already adds control effects and makes him deal a good amount of more damage. The full set makes him basically double-ult if needed.

Recommended Artifacts
Duras Eye is the best artifact to run with Raku in most cases, although you can also consider running Verdant Longbow or Duras Blade as backups, depending on your team setup and what artifact you have available.
Engraving
In terms of Engravings, your final goal should be E44. (but you can also get the first sweet spot at E16). His engravings favor his Haste, Crit and Physical Pierce well and that helps him take out tank heroes faster. For beginner, start with investing in his DEF and HP major nodes and then in the minor HASTE and ACC nodes. The goal I see for him is E44 which prolongs his buff and benefits from the first Engraving effect and the stats work really well for him. Learn more about my recommended engraving priority here.
