4. Sejuani
Sejuani is a tanky jungler that has potential for great mid game ganks. Sejuani has a slow and a stun that will ensure the enemy will not get away. Sejuani is able to clear the jungle fast in the early game and get into position for ganks easier because of her Arctic Assault, which can not only get over walls but also knock up and slow the enemy. If you are looking to get better in the jungle, Sejuani is a great pick. Her easy playstyle allows you to get comfortable in the jungle if you are a beginner.
Since Sejuani is mainly a tank you don’t have to worry about building too much ability power. Sejuani is very helpful in team fights for just stunning and slowing the enemies. Since you will want to build mainly tank, I would reccomend build an Abyssal Scepter and a Rod of Ages. By building those two items you are able to have a decent amount of ability power, and health. After those two items are built you can start to lean towards more tanky items like a Frozen Heart or Randuin’s Omen…unless you really need the extra damage, in which you could build a Liandry’s Torment or a Rylai’s Crystal Scepter.
