ZOMG. I'm a newly starting Jungler as well, and the shift in the jungler meta is just so ARRRGH for me. I keep getting killed in the jungle(Do mind- I almost never give the enemy team kills :P[okay, just a too much exaggeration :P])
So here are the stuff I found to be REALLY helpful:
1 Masteries:
Having the masteries in defence just enough to get bladed armor, enchancted armor and tough skin is a bliss. Helps you survive the through beating oh so good.
Potions are actually being used in the modern jungle now. Well that's a plus. As ww, I'd wonder when I'd actually use my 5 pots in the early jungle :P
2Runes:
WHAT?! Runes?!
Yea. Well, I'm almost 14 now, but I've actually bought a full set of runes(tier 1) just so that I can have a little better time jungling that that random 1350 IP. Yea, yea. I know that ppl will laugh at me when I say I bought runes, but it doesn't hurt so much if you take some arm pen or armor or health runes, so that you'll have a infinitesimally better jungling. Take a quint, and some marks/seals, just a few, so that you can enhance your jungling by a bit
- Focus
Focus on more sustain based champions, or champions that are ridiculously good at clearing maps. But right now, I'd advice playing Fiddlesticks, nunu, warwick, and yi (But he's really hard to do anything without runes, tho. tbh). Once you get like 13 mastery points and a few runeslot, you'll be able to play more complex champs and champs with no sustain.
4.Leash
Ask for a heavy leash, so that you don't have to use health pots. But do signal ur frens to retreat if the minion health is falling too low- they'll get the experience for the monster if they're around it when it dies too. That way, you'll at least be able to clear two camps( i.e., 2 lvls) before u b and buy ur advanced jungler item, a ward and some health pots.
- Ranger's Trailblazer
Yea, that chilling smite, or that challeger's smite MIGHT seem attractive, but rangers actually gives that small HP/mana reward on smiting a monster. Make sure to use it so that it's less hectic.
6.Path:
Say you're going to take blue all alone. You'll die 100% if you've got no pots/sustain. So what do you do? Take the neutral camp buffs. Stuff like that gromp's poison/that mini golem's stun are so useful that you'll mostly smite them than other stuff. Do note that those buffs can be acquired without killing the monster. Just smite and scoot. Also, don't take on those raptors unless you're like 100% health, or with healthpots and/or lvl 4+. They'll slowly pluck off your flesh and kill you.
7.Worst Case scenario: Take heal.
Yea, it's lame. But atleast they won't laugh at you for dieing to a buff :P
All in all, be really wary of invades and stuff. NEVER walk around with 50%- health if you've got no escape spells. As shaco, I take heavy leash + 3 JITBs on blue, go over to enemy red, take it and then I wait at the raptor bush with as much as JITBs as I can muster. I just ignite, then aa the champ, so that either I get a) a successful flash with health pots burnt and me having a psychological edge. or b) I just keep poking him with my aa whilst he's feared + running away till finally when he gets my e and gives me first blood, STILL giving me the psychological edge.
People are too careless when they go inside their own jungle. You never know what pops out and kicks ur butt hard :'(
