What junglers are good at counter jungling or invading

These assholes

Rek'Sai is pretty good. She can check if the camp is taken before moving in, and is a decent duelist early. She can also move out after counterjungling relatively safely.

Nunu is also amazing with the true damage nuke on monsters.

would like a word.

I do it a lot with nocturne

Shaco!

I feel invincible when invading.

1. You have boxes that can disrupt a chase or give vision over walls.

2. You have a slowing ability, and it's not a skill shot!

3. Invisibility. Walk in, see five enemies, pop back out.

I'd tell you a couple more, but they're literally worse than Hitler, and using them against an enemy player is a crime against humanity. I simply cannot condone their use against actual human beings.

I would suggest jungles who can leap over walls. Nid might be good if you plan out your traps.
