A list of all the characters that can, in my opinion, effectively jungle at the moment
Standard items: Cloth Armor + 5x potions

Best Jungling Runes:

I use Armor, Attack Speed, HP for jungling.

The glyphs are dependant on the champion, but are somewhat useless.

Masteries:

The standard jungling masteries are 1-16-13 or 1-18-11, going for Mana Regen, HP, Smite, Ghost, Armor, and the XP masteries.

I however, tend to use 1-13-15 (Movement speed) for faster jungling, on characters like Rammus that do without the defensive masteries.

For invidual jungling guides you can ask me. These are, in my opinion, the current characters that are intelligent to jungle with. Some are better, some worse. I'm pretty sure EVERY character could go in the jungle, but not as effectively.

you forgot blitzcrank and cho

pls can u tell me the best runes for each slot for jungling champions in general.

Flat Armor Seals are the best jungling seals, in my opinion.
After the upcoming patch, you could consider Evasion too, because the Random Number Generator will be less random, resulting in more reliable Evasion.

If you're playing a physical dps jungler, then Armor Penetration Marks should be the most flexible choice.

The rest of the runes are dependant on your champion, especially Quints.

But after you got your full set of seals, you're good to go.

I was thinkin attack speed marks (synergy with many jungling champions abilities, synergy with madreds item procs) + dodge seals (better late game potential than armor runes and mobility activation) + cdr glyphs + hp quints.

Another of these lists without Corki, what a fail.

Adding Corki, Blitz and Cho.

Also added runes for each, but I don't know the rune setup for some champions.

Do tell me if you know.

Trundle. All he needs is a Vamp Scepter and he can jungle without having to blue pill ever.

Karthus. He's strong on lane though but can be very surprising and ulti from brush = imba
