If you want to make Kren 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 Kren 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 Kren does in the current meta of all heroes in AFK Arena, please check out my current tier list of all heroes here. Kren’s Signature Item
Kren’s Signature Item should be at +20. Kren’s Signature Item simply makes his ability stronger at the very basic so super strong. Also the stun of the +20 Signature Items is great. The +30 isn’t that necessary.. 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 Kren’s 9/9 furniture set bonus. Kren’s furnite is a tough spot, invest vs benefit… 3/9 brings okay protection and will become better crowd control at 9/9 which will help him stay alive. Actually not a make or break in most battles so optional for me and his scaling damage is what you’re after later in the game so not a invest to overly prioritize early on.

Duras Call is the best artifact to run with Kren in most cases, although you can also consider running Verdant Longbow or Duras Eye as backups, depending on your team setup and what artifact you have available. Engraving
In terms of Engravings, your final goal should be E61. (but you can also get the first sweet spot at E13). Kren is the key here in the Mauler faction and he really requires that haste so for beginning, get into his DEF and HP nodes to 5 and then into HASTE for additional 3. From here 5 into all major nodes and 3 in all minor nodes and the 3 extra in the HASTE node to get the bonus energy for every detonated mine on the field to make his ultimate skill cycle faster. E61 is for ned-game and results in much more survivability with more haste. Learn more about my recommended engraving priority here.
