Just spaced putting points in dredge line 1 point at lvl 3 ll

Adding points in dredge line wont make it go further, so not important, if your doing well frozen mallet very attainable, also the builds specifically for a high ad match, te build works for me, and Iv won many games with it, however thanks for the picture thing I was a little lost there, ill look into it.

This is gonna need some work. First off you need pictures. To do that go to the top right and go the BBCode guide. That will tell you how to put images into your guide. Frozen Mallet on nautilus is a bad item choice as it takes forever to build and you already have a ton of slows, snares, knock ups and bleeds. Secondly Health marks are terrible on nautilus as he gets tanky already. Replace those with attack speed quints. It will give you more DPS and make you more of a threat in fights. Your build also lacks a Magic resist item which is a major thing on Nautilus!! imagine him with an abyssal scepter not only providing a helpful aura destroying their MR but also dealing out damage with Riptide. Or Wit's End imagine the damage of reducing their MR and hitting them with a bleed at an attack rate that hits at least once per second plus with attack speed runes it would make it scarier. Lastly you have no points Dredge Line which is part of ganking!!
