Hello everyone, I am Insightful a multi season Challenger player in the EUW server and recently morgana jungle has come out as a strong pick in both proplay and soloq so I've decided to write a guide about it to help those who are interested in giving it a try! I've reached challenger twice this season on 2 different accounts and hopefully I'm able to pass some knowledge to you guys aswell.

Morgana Despite being mostly a support champion, recently riot has given her a few changes to make her a viable jungle, as a result she became a very dominant champion in both proplay and soloq as a jungler, despite recieving a few nerfs, the overall result was still a buff from what she used to be, she has a very fast and healthy clear due to her passive, she never loses HP while clearing camps and she has very strong ganks and teamfighting too, she has a decent amount of damage and can peel for her carries aswell.

Code:

Pros → fast clear → good ganks → can start fights → Has a lot of crowd control → Very healthy clear → You can peel for your teammates → very safe jungler, hard to get caught

Cons → not a very strong duelist → Doesn't really have kill pressure 1v1

Soul Siphon
Her passive is what makes her able to clear the jungle,she has lifesteal from her abilities and it works on large monsters, it's a great passive to always keep you at full hp while doing camps. Dark Binding
Her Q is basically a projective who roots enemies in place for a VERY long time, it's arguably her most important skill since you need to hit it to make your ganks successful and to make sure they take the damage from your W. This is the 2nd skill you will max. tormented shadow
Her W is an AoE ability who does damage every second an enemy stands on it and at the same time for each enemy on it, it reduces the cooldown of it by 1 second. It's the most important skill to clear jungle camps and it's the one you will max first to make sure you can clear fast and stay ahead in tempo. Black Shield
This is one of the reasons why morgana is such a good teamfight champion, her blackshield gives a magic resistance shield who blocks every form of crowd control while the shield is active, time it perfectly on your carries and enable them. Or use on yourself to avoid getting caught in a bad situation. Soul Shackles
Her ultimate ability is a 2 part skill who deals damage and stuns on your enemies on the 2nd part. It's her best ganking tool after level 6 since if you get close enough you can cast it and then you need to stay near your enemies for 2.5 seconds to deal damage again and stun them to enable the rest of your kit and make it easier to land your Q and W.

Dark Harvest: As most ap junglers, dark harvest is the best rune for morgana, she has damage over time with her W, plays from the distance and can proc the rune multiple times in a fight. Cheap Shot: Morgana doesn't have a way to proc Sudden Impact so this rune doesn't make sense for her, and you're not laning against champions so Taste of Blood is also useless, so by elimation Cheap Shot is the best rune and synergyzes well with her kit, since she has a root and a stun to proc it's extra damage. Eyeball Collection: It's the easiest rune to stack out of all 3 as a jungler so you take it. Relentless Hunter: Since Morgana has a lot of sustain from her kit and doesn't really get any active items Ravenous Hunter and Ingenious Hunter aren't really useful, and her ultimate doesn't have a very long cooldown so we don't need Ultimate Hunter aswell, Relentless Hunter is the best choice because it enables you to move faster around the map outside combat and look for potential ganks. Nimbus Cloak: This rune is very helpful for when you get close to enemies you can have extra movement either to gap close or run away from them since your champion lacks mobility. Transcendence: The ability haste provided by this rune is very helpful to make sure you can spam more abilities during fights and provide your team with crowd control and utility.

Liandry's Anguish Morgana can use all the AP items but this one is the one that stands out in my opinion, due to the DPS that it provides the extra DPS to synergyze with Tormented Shadow and the mythic passive gives her extra ability haste so she can use more abilities.

Zhonya's Hourglass This item is core because it has amazing synergy with her ultimate ability Soul Shackles, you can cast it and then you need spend 2.5 seconds near your enemies but with zhonyas you can just press it and it mantains the bond without you being at risk of dying.

Demonic Embrace It works in a very similar way to liandry's but it also provides some defensive stats which are very helpful to make sure you don't get one shot by everything, while giving you extra damage over time that you already have.

Mejai's soulstealer It's a snowball item, if you're feeling confident and you have 10 stacks on your Dark Seal go for it!

Rabadon's Deathcap If you need to provide extra damage for your team, this is the perfect item to make the most damage out of your abilities, but it's very expensive so you don't really want to build it early because it also gives you extra AP based on how much AP you have.

Morellonomicon If the enemy team has a lot of champions who heal such as Yuumi, Soraka, Vladimir,etc... someone on the team needs to get that heal debuff and Morgana has a lot of AoE so it doesn't hurt to buy it.

Void Staff Once the enemy team starts stacking magic resistance, Void Staff is the item you need to make sure your abilities's damage don't get mitigated.

Morgana's jungle pathing is pretty simple, you can start anywhere and you always want to full clear, a small trick that you can do is try to do multiple camps at the same time such as Red buff & raptors | gromp & blue buff. Once you full clear, you want to get the nearest scuttle and try a gank.
That's pretty much how to play it out, she has a very healthy and fast clear and you have plenty of time to see where you want to gank!
