The 1v9 bruiser

This build and game play are really strong in lower-ello. In situations where the enemy botlane is going 6/0 and your botlane is talking in chat in a language you didn't even know existed, This is the way to go. You've got HP to tank demage, and you've got enough demage to execute enemies. I usually get behind enemy team and try to kill ADC first. If it's a fight in mid, I just go in first; I use Ghost before. And when my eclipse shield activates, I fall back and look for another approach. These few seconds are enough to delete their adc or any other squishy carry. The shield you will get from you R, mosstomper and Eclipse will be crazy. This is why you can jump in kill someone or start a fight and leave someone low and come out alive. And the ghost is just a cherry on cake for this.

Freed from desire

Naafiri is quite broken right now. The w is really strong catching enemys. The champion is pretty simple. I ussualy use w - q - e - q. This is the main combo you will use. For example you jump on ashe, you use w, than q,dodge her R or W with your E and you will end up behind her, and q again. If you have first 3 items she will be deleted. Use r mainly to steal drakes or barons and in team fights. It gives the vision and movement speed to dodge stuns and smite it down, or escape after engage.

GUARDIAN ANGEL

The build is really strong, this is the way to go when you are the carry and you need to end quickly, ussualy happens when enemies have kayle or other champions alike. In this case when you start a team fight you go all in. When u would kill 1 champion you end up killing 2 at least. In mean time your team leave the rest low and you finish them This is why guardian angel is important. Because in late game when everyone is equal nafiri loses a lot of adventage.

Smooth Operator

I go full clear with naafiri. I start Q and go red, after red I take E, jump over the wall and do krugs, than raptors, after raptors you can eather gank mid, or you can finish clear. Than Wolves, you use smite on blue buff, than gromp, and scutle crab, and you feel free to go into enemy jngl, gank top or recal and buy

The Tax Law

The Tax law is really simple. For every objective or gank enemie jungle did he has to pay taxes. Your bot got ganked and killed, they are going for drake. Instead of trying to steal it. Go for rift, if there is no rift go steal his jungle, make it your home. Go gank top. You see hecarim ganking top, you go into his jngl make him pay taxes, than you free to gank bot and take drake yourself. This is more of a mindset that i like to have when i play jungle. But its not posible all the time. Some times you are behind or enemy jngl is fed and the right choise is not to risk feeding him more by going in his jngl. Sometime is fine to farm your own camps and give them some objectives.

Naafiri doesn't really need flash. When i started playing her i used flash and it wasn't really usseful. I wanted to change for ghost and i think this is the best fit. It's really strong in team fights when u quickly need to catch few targets or run away, its the best.
