I'm maining Nautilus and he's a beast as supp. Just read your guide and it lacks some items. For instance, if you are ahead you dont need to buy items like redemption. Zeke or Knight Wow depending on enemy composition and then go for Warmong or another tanky item.

Also, your priority is to up you Q and your W. Nautilus E is not as good if you go supp, just my toughts.

Comment on runes: I think there are better options. First, I agree that Nautilus should definitely be running the resolve tree, but Overgrowth isn't really that great, especially in a build like this that doesn't focus on stacking a ton of bonus health anyway. I would recommend Second Wind instead, as anytime you engage you will be taking some damage in return, and it helps better sustain through most phases of the game. Second, While I like the inspiration tree, I don't think it's ideal. Instead, I'd recommend domination with Cheap Shot (and get your ADC to run it too), and either Zombie Ward for extra vision or Ingenious Hunter for active item CDR.

Heya! Did you know you can hardcode anything from the MobaFire database by adding double square brackets? Like this Nautilus :) [[nautilus]]
