(EDITORS NOTE: ALWAYS USE YOUR EMPOWERED Q TO CLEAR. WHEN DOING CRAB EARLY USE EMPOWERED W BUT IF HIGH HEALTH USE EMPOWERED E)When you start your jg clear if you can always go to Krugs first. I find 3 pots helps your early clear way more than the refillable. Smite krugs early (if ur not getting invaded) and use the stun and you q to ur advantage. Max w and do rapters. Kill the little ones first, but make sure when the krug stun is up use it on the big one. Once you are done head to skuttle. If you have cleared properly and efficiently you should be a second away from the middle of the river when scuttle spawns. By this time you should have popped only 1, max 2 of ur pots. If you have the lifesteal mastery and you use the krug stun effictively you will kill scuttle relatively fast and gain a lot of health. Next go back to your red. Your krug stun should still be up for 1 or 2 stuns. Use it and the smite heal and with using 1 or 2 potions you will arive at wolves with most of your health. Now proceed to clear wolves blue buff, gromp and skuttle crab. When you are finished all of this you should have used all your pots and still have a bit of health. You can now gank or back. From here on you just keep on clearing and ganking.

When ganking with rengar you must keep a few things in mind:
1. Do you have your ultimate?
2. Does the laner have flash?
3. How many stacks of ferocity?
4. Do you have flash?
5. Can you use a bush to jump?
If the enemy does have flash, then your safest bet is to empowered bola. If you dont have ult, flash or a bush to jump from, empowered bola is also worth it.
If you do have ulty and the enemy doesn't have flash then you can go ahead and use your one shot combo (see below).
The safest option usually is to empowered bola.
A tip for ganking mid with flash and without ulty:
Go into one of the side bushes and flash over the wall, angled towards the lane. After you have flashed empowered bola the enemy to provide some epic ganks.

With this build you have a certain combo that if pulled off correclty on a squishy target should zero to one them. If you have a sweeper use it first and clear any wards found. Now proceed to ult. Once you are relatively close to your target or if you need more speed to get to them use your youmuu's. Before you jump use your empowered q, and a second after you start jumping use your bola. As you land use your w and ravenous hydra/tiamat if you bought one. If the enemy has any more health (which they probably won't) proceed to auto them in the space of a millisecond with the attack speed from statikk, phantom dancer and youmuu's. At this point they should be dead unless you are very behind, they are tanky or you just arent very late in the game.

There are a few things you want to do late game before teamfights.
1. Go around the enemy or your jg and clear everything. In the late game with this build you will basically one shot the jg creeps, so this isn't too hard.
2. Go back and by anything you can (red pot late game)
3. See if anyone is split pushing and proceed to one shot them (without ult if you can)
4. Now enter the teamfight with a 4v5.
In a teamfight you want to focus the squishies. Ask your team who they want you to kill (if they don't answer just use your brain) and ulty if you can and jump on them. Use your one shot combo to annhialate them. After that just help your team clean up. If you don't have ult try and go around the jg to go behind the enemy team, and kill their backline that way. This should lead you to easy wins :D Thanks for reading my in-depth guide to AD Rengo JG, now go into a game and one shot some poor adc soulds!
