I just bought him, played a bot game, and... my build seemed a little off... or a lot off. Was stupid powerful early, got a triple kill with one E at opening Windmill fight, and was just ruining people early, but late game it didn't seem like my items were paying off, and while I still managed to get kills some times and never died... it felt like I was just coasting from the early game monstery.

I did a WuKong build on him, and while it makes sense, it seemed like maybe a more ADC build would be better on him for late game?

Get CD boots, Brutalizer and rush a Last whisper, FInish Yoomus, then get a phage, evolve phage either in Fromal or entropy.

its bots

Mallet only affects his autoattacks, but every AD caster is also a solid AAer(because for every champion in the game scales 100% with autoattacks). Pants should be AAing, and a Mallet gives him sticking power and toughness.

Edit - I've seen some non-traditional Pants builds that involved attack speed, HP, lifesteal, and big AD...the result was that this Mantheon did massive damage while literally being unkillable...you couldn't hurt him because of all the blocking and he was too tanky for mage burst.

Oh, can his E crit?

Oh wait, I know the thing:
