Hello this is a guide to nocturne the eternal nightmare. Nocturne is a strong ad burst champion but is squishy. In this build I will show you how you can have lots of health without being losing your ad.
Note: This build does work with jungling just remember to get smite instead of ignite.

These runes will be needed in order to be tanky and ad at the same time.

Greater Mark of Desolation: The armor penetration will make you do more burst damage on enemies.
Greater Seal of Alacrity: Great for farming and using your burst damage as an advantage.
Greater Glyph of Replenishment: These runes will let you spam skills in the beginning.
Greater Quintessence of Strength: Used to fit your ad burst damage.

21 0 9 is the masteries taking mostly ad burst damage and the speed to escape.

Some of these items are all for burst damage while some items give you health and attack damage at the same time.
