Hey, this is my first serious guide on mobafire. The build is about Rengar, the PridestalkerPlease show me some support im noob on making guides (I dont mean the guide is useless)
Works great in ranked and as solo top it's like the same build but change your smite to flash.

Early game!
[*] Start with Boots of Speed and 3 potions for early ganks!
[*] Start with Regrowth Pendat and 1 potion for longer survival in the jungle!
[*] You can start with Clothc Armor too if you want, but I prefer Regrowth Pendat and 1 potion.
After your first Recall you should have Mercury's Treads and a Wriggle's Lantern and maybe Bonetooth Necklace. (or you can pick up Ninja Tabi if you want some extra armor and the damage reduce)
Mid game
Now you should have your Warmog's Armor, Atma's Impaler and a Force of Nature.
At this time you are going to be more tanky so you should take the lead in teamfights, but don't just dive in and think you are rambo because you are a predator, a stealth tank what more need to be said?

Late Game
Sell your Wriggle's latern and buy a Frozen Mallet. Now you should have a good amout of health regen and armor and magic resistens. Lead your team in to the fight and win with style, because you are a predator!

[*] Pick 9 Greater Mark of Strength for a damage boost in the start! Then pick 9 Greater Seal of Resilience for the armor boost! After that you pick Greater Glyph of Shielding for the magic resistence boost! And for your Quintessence pick Quintessence of Desolation for the armor penetration!

Unseen Predator While in brush or stealthed, Rengar gains bonus attack range and his attacks cause him to leap at his target. This bonus lasts for ~0.5 second upon exiting brush or stealth. This will happen regardless of whether or not his target has sight of him, and has no internal cooldown.
Range: 600, 750 with 9 trophies on Bonetooth Necklace.
Savagery Rengar's next basic attack deals bonus damage and grants him increased attack speed for 3 seconds.
Cooldown: 6 secondsEmpowered Savagery Ferocity Bonus: Savagery deals additional damage equal to 150% of Rengar's attack damage, and the Attack Speed bonus is doubled.
Cost: 5 Ferocity
No cooldown
Battle Roar Rengar lets out a battle roar, damaging enemies and gaining bonus armor and magic resist for 3 seconds.Empowered Battle Roar Ferocity Bonus: Battle Roar also heals Rengar for 15% of his maximum health.
Cost: 5 Ferocity
Bola Strike Rengar throws a bola at his target, slowing it for 2.5 seconds. The slow decays over the duration.Empowered Bola Strike Ferocity Bonus: Bola Strike initially roots his target for 1 second. The slow is applied in full after the 1 second, and decays over the remaining 1.5 seconds.
Cost: 5 Ferocity
Thrill of the Hunt Rengar activates his predatory instincts, stealthing himself and revealing all enemy Champions in a large radius around him. He gains movement speed and generates 1 Ferocity per 0.75s while stealthed. Lasts 7 seconds or until he uses an ability.

Pick Smite because your a jungler and Exhaust for the extra slow and damage reduce!

The jungle riot is simple begin at red buff let some of your teammates pull it to take less damage when the Lizard got half HP use your smite, after you have cleared the Red camp go to the Golems then go the the Wraith camp after that the wolwes, and I like to give the blue buff to the mid laner because you dont need the mana regen or the CD. When you hit level 4 start looking for ganks!

[*]Pros
-Good ganks!
-Tanky late game!
-Easy to handle! (for me anyway)
-He is a predator!
-Invisible ganks/Leap ganks!
-NO MANA NEEDED!

[*]Cons
-Slow jungling from start
-Hard to handle sometimes! (I know what i wrote up there)
-Slow base attack speed!

More pictures and maybe a video will come!
