PROS
Insane Scaler and outscale most of the junglers in the current meta
Iverns Pathing is hard to track due to no leash
Strong Ganker
No Leash needed
Really good pick if you have teammates that can play around you and enable you
The champ has alot of good synergies especially w/ most Bruisers

CONS
Weak, first clears and very vunerable
Vunerable in jungle if enemy jungler perma invades with full prio.
Needs a carry
Hard to learn to his full potential

There is 2 pathings I do, depending on the teams win condition and enemy jgl.
1st.
Red - Raptors - Blue Smite - Gromp - Wolves - Claim Raptors - Claim Red - Claim Wolves - Claim Gromp - Into gank / scuttle.
2nd.
Wolves - Blue Smite - Gromp - Raptors - Red - Crugs - Claim Gromp - Claim Wolves - Claim Raptors - Claim Red - Claim Crugs - Into Gank/Scuttle

So how i decide what path to chose depends on if enemy jungler is a heavy invader, If so you need to play smart about your pathing trying to avoid him on the map, he starts blue you start blue, Try to avoid on map like forexample Rengar, Graves, Nida ETC. Then you need to analyze your team comp and look for the wincondition and play strongside for that lane.

[*] Moonstone Renewer and Staff of Flowing Water are the core items of Ivern. These are the items you want to rush every single game, after you rush the core items there's alot of options you have. It all depends on the game and you will have to analyze the game situation for yourself. Some options are Ardent Censer, Redemption hard engaging teams on enemy, Mikael's Blessing Alot of CC on enemyteam, Zhonya's Hourglass is for hard assasins so you can stay alive in teamfights and even Chemtech Putrifier against teams with alot of healing.
