Udyr

Aggressive jungler, he can just walk in and steal your camps and kill you. You have to have vision, if you see him, it's best to try and get your team to collapse, and if they don't, well just give the robber what he wants and let him go. You cannot 1 v 1 him.

Kha'Zix

Another aggressive jungler, same thing as udyr, ward and pray he goes away, or you're gonna be prey.

Ekko

So Ekko is a semi-aggressive jungler, he can just walk in and steal your stuff, but you can put up a decent fight if you're good, still call for help cuz he's a free kill pre-6. After 6 he can be pretty annoying, just avoid his ult area and you could probably 1 v 1 him. he moves fast though with his passive, so be weary of that.

Elise

Even as well, honestly most champions can just walk into your jg and take your stuff, amumu is pretty squishy early and reliant on teammates who will back you up. Just watch for her human e early game and her spider e late game because she can avoid your damage if she reacts fast.

Evelynn

So her early game is pretty weak and her late game strength isn't much of a threat to you, if you see her mid to late game, as long as you know where much of the rest of her team is, just q and ult her, she should die pretty easily. Free drake or baron or turret. her ult can be troublesome if you don't kill her, but she shouldn't do too much damage to you unless she's super fed, so you can start a fight with your team without her present for a little bit, her passive does heal her a bit though.

Graves

Graves is pretty weak early, he's a good duelist though, so still be careful. call for help if you see him in your jungle.

Hecarim

hec will also invade you and kill you if you let him. post 6 you should be able to defend yourself a bit from him, but he can probably still one shot you with a full rotation and q's.

Lee Sin

Lee can stick on you pretty easily. Amumu is already immobile, Lee can just q onto you or just walk up to you if you're out of position and e you and just keep auto attacking you and if you flash he can q onto you. Get good with awareness of your camps and use them to q away from him.

Ivern

Ivern is rarely ever a threat, his late game cc and tankiness can get annoying, but you should be able to play around him easily.

Jarvan IV

Pretty good duelist, can walk into your jungle and get out just as fast after stealing farm.

Gragas

You can be one shotted and be the one shotter. he does have some sustain with his w, but he shouldn't be able to just walk into your jungle and put up his flag. As with all invades, call for help from your team.

Kindred

'Extreme'ly annoying, her ult counters your damage if she reacts and knows your damage. Need to play around her or get her out of teamfights before they start. She wins 1 v 1 throughout the game.

Kayn

Invades, aggressive jg

Nocturne

beats you 1 v 1, can shield your q and kill you early, late game you can just ult him after his shield and if he doesn't shield then he can just die

Nidalee

Invade invade invade ward your jg

Fiddlesticks

he has a lot of healing, but you have 2 hard cc spells, just wait for him to heal or just kill him, he's pretty squishy throughout the game.

Olaf

his ult counters your existence, super tanky, heals a lot, good use of morello's

Karthus

One of the only jg's YOU can invade. he wants to full clear and he normally starts blue, so if you don't see any available ganks after red side clear, go blue and go to his red and kill him, should be around there somewhere

Master Yi

annoying all the time, bane of my existence. Need to lock him down so your team can burst him in fights, easy to fight against, but you can't ever fight him alone unless you're super ahead.

Pantheon

Panth can just block your q damage, I don't think he can block your w damage though, just lock him down and your teammates can deal with him after his w is done

Rek'Sai

I've been playing a bit of Rek'Sai recently and she can just invade you and see where you are with no wards and e over the wall and kill you. Stay healthy in your jg. Don't flash after 6 and you're low, she will still get you.

Rengar

You can lock him down easily, just play inside the bush, make sure you're right in the middle of it.

Shaco

Shyvana

Early game isn't a problem, you can probably 1 v 1 her, mid and late game can be annoying if she went ap, if she went ad just kite her with w.

Vi

Vi is currently s tier, you don't 1 v 1.

Volibear

I always ban volibear rn

Warwick

ww will hunt you down if you are seen, make sure to back when you're low after ganks, unless you have smite for hp
