The BUILD 1 IS MINE.
BUILD 2,3,4 ARE TOP 3 NOCTURE'S BUILDS.

BUILD 1 : 14 829 G

+ Pros :
- Health
- Damage
- Attack Speed
- The Black Cleaver : Physical attacks reduce your target's Armor by 15 for 5 seconds (maximum 3 stacks).
- Warmog's Armor : Permanently gain 4.5 Health and .15 Health Regen per 5 sec per minion kill. Champion kills and assists grant 45 Health and 1.5 Health Regen per 5 sec. Bonuses cap at +450 Health, and +15 Health Regen per 5.
- Sword of the Occult : Your champion gains 5 damage per stack, receiving 2 stacks for a kill or 1 stack for an assist. This effect can stack 20 times; you lose a third of your stacks if you die. At 20 stacks, your champion's movement speed is increased 15%.

+ Cons :
- Mana (Really necessary? I've never missed it.)
- Armor penetration (Attack Speed and Damage balance.)
- No passive (Stun, cd reduction, [target's movement speed reduction, because mine is better], no block spell every ... secs, [no revive champion, because I've got lots of health points so I normally don't have to die], [increase the attack speed because mine is ALWAYS very fast].

Choice: The Black Cleaver can be replaced by a Bloodthirster if enemies have low armor and can be easily killed (for stacks , like Sword of the Occult), otherwise The Black Cleaver is more profitable.

BUILD 2 : 17 750 G

+Pros :
- Mana (too much for me)
- Armor penetration
- Youmuu's Ghostblade : You gain +20% movespeed and +50% attack speed for 4 seconds. Attacking enemy units with melee attacks increases the duration by 2 to a maximum of 8 seconds. 60 second cooldown.
- Frozen Mallet : Your attacks reduce your target's Movement Speed by 40% for 2.5 seconds (30% for ranged attacks).
- Trinity Force : 25% chance on hit to slow the target by 35% for 2.5 seconds; on cast, your next attack deals bonus damage equal to 150% of your base attack.
- The Bloodthirster : Gain an additional 1 Physical Damage and 0.25% Lifesteal per kill. Maximum of +40 Damage and 10% Lifesteal. Bonuses are lost upon death.


+Cons :
- Armor
