Hello, I am Valcarian i am a player on the Oceanic server my account has been up for a while and i have recently reached level 24 and i decided that i should try and get a build up to help other players get to know Nautilus, Personally i never found Nautilus a challenge to play but i had allot of previous experience with Thresh and Blitzcrank and i chose to play him quite Tanky which i have seen not many people use him as a Tank or as a support, he has quite high physical damage as he levels and if you build high amounts of health behind him you will find that he can take allot of punishment from other champions and come out on top. My play skill and ability aren't all that great but i have quite good matches with Nautilus, some of my best, and from about level 5 i've been playing Support and Tank class Champions with the occasional Ziggs Mid and Warwick jungle, I have always enjoyed champions that deal high damage very fast but i also enjoy a champion that knows how to be hit and hit back.

The Runes are more like Guidelines then what you should probably use, i'm new to all this and i chose what i would use if i was to play Nautilus how i have shown (which is actually how i play him). Nautilus relies strongly on health when he is solo which is why there are so many Health Runes, also i added a few Physical runes in case you had to fight your way out of a tough battle where you are outnumbered or against a fed enemy champion.

Depending on what stat you need the most, AD, Armour or Health you can choose replacement items to boost those stats to what you need for the battle, i have no hint other than that so that purchase is up to you and you alone.
