Venom jungle is crazy right now. here are some tips:
First of all you need to convince your teamates that you are not grieffing and well.. this is the hard part of the game.
also your safelaner is going to play solo in the lane. which is gonna be hard for him. so just tell him to play as safe as possible. block the hard camp for him so he can pull the lane creeps in the easy camp and farm safely. also gank his lane after level 4 and make him happy. so realisticly he is going to have a hard time for about 5 minutes.
aura items are your friends. buy them all
gank lanes as much as possible
run away from camps when you're farming in early game so you don't have to buy regen items and you only buy clarities
also at lvl 15, get the 15 talent and then get the lvl 10 talent at lvl 16
