If you want to make Oscar 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 Oscar that will give a big boost so I have some recommendations below that you will very likely find interesting.
Oscar’s Signature Item should be at +30. No doubt that his Signature item ability is useful to have here and there, but it’s simply too expensive to build looking at the rare use cases when you even have an enemy hero that can go behind your backline. Still, looking at the meta you will not see this hero play any significant role towards late- or end-game so save up the emblems. You can maybe get the +1 to unlock the skill if your eally want to, but that’s it..

Furniture Recommendation
Overall it’s recommended to get Oscar’s -/9 furniture set bonus. Oscar The dodge added with 3/9 is nothing that you will actually feel in fights at all and the damage increase of the 9/9 furniture bosst is alright but not worth such an investment for such a hero.

Recommended Artifacts
Duras Eye is the best artifact to run with Oscar in most cases, although you can also consider running Shroud of Verdure or Duras Blade as backups, depending on your team setup and what artifact you have available.
