SPAWN
So when you spawn of you choose between the normal spawn and the team spawn. you choose the normal spawn if you are farming with a protector because they should be getting an ironguard contract and so you wont have to. but if you are farming with a squishy hero than you should get the team spawn so that you both get enough gold and so that you don't run out of health because there aren't enough healing creeps to share.

ENTERING YOUR JUNGLE
When you get to your half of the jungle you should ping your ally to come and help you with clearing out the camps on the other team's side, starting with the ones that will be next to the jungle shop when it spawns. if you see the enemy already there, than attack them because one of them will either be missing health or have the creeps already attacking them, meaning it will be almost impossible for them to win. one they have retreated or been killed, than finish of the creeps and take the camp nearest to you, which is a healing camp. once you have done this, retreat into your jungle and farm until the jungle shop spawns, unless your laner needs help (he shouldn't).

4 MIN
once the jungle shop spawns, you should have enough gold to buy a six sins and heavy steel. any leftover gold you have you should spend on a blazing salvo and scout traps. continue farming.

10 MIN
By this stage in the game you should be around level 10 and have tornado trigger and sorrowblade, as well as a defense. Work on building tyrants monocle. The game will no longer be focused on farming, and more on team fights/skirmishes. you should stick with your team and take the monster camps when you pass them.

15 MIN
basically just team fights. Work on finishing tyrant's monocle and then sorrowblade or serpent mask, and finish of you boots and defense, if you haven't already. Be extremely careful not to get aced because they will get the kraken!

END GAME
When I say end game, I mean when you are maxed out and spamming weapon infusions. At this stage anyone you catch away from their team is as good as dead. In team fights try and use shimmer strike at the start, to negate most of the initial burst and force the other team to attack you allies, then jump on their carry at the end of shimmer strike and kill them, then just destroy the rest of the enemy team with ease.
