When jungling do you kill the large creep first or the small ones???

Small creeps first usually

Small Krug before big Krug unless you're getting a leash Small Raptors before big Raptor Wolves it doesnt matter unless you have AOE (about the same damage taken either way), but kill the little ones first if you have some AOE to help. Buffs it doesnt matter (about the same damage taken either way) but generally its better to kill the buff first unless you're leashing for your mid.

If you have strong AOE it's still best to direct your auto attacks to kill the little ones first.

Dude there is literally a stickied topic called optimizing your jungle clear that tells you what to clear first in each camp. For wraiths you kill the small ones first, krugs you kill the small one first too, and all the rest don't really matter (sometimes if you have good aoe dmg its better to just kill the small ones and then focus the big ones). Also if you have a reset mechanic like irelia's q you should kill the small ones first for your resets. Here is the link: http://boards.na.leagueoflegends.com/en/c/tips-tricks/ER5sX6rm-the-climb-optimizing-your-jungle-clear

if it's raptors kill the little ones first, other than that always the larger ones

depends on your aoe amount of aoe the more aoe the less you have to focus the small ones

depends on a few things what jungler are you what level are you and are you in your or the enemy jungle

if you are in the enemy jungle you always kill the big one first, you might decite to not clear the smal one at all or might get found before youd be able to kil it if your higher level you usualy just kill the big one first

but on most junglers first clear especialy its easier to kill small chickens and smal gromp first wolves doesnt really matter and on buffs kil the buff first

depends on the camps and your jungler type.

A single target clearer like Warwick does it differently than any AoE clearer such as Diana.

For AoE clear champs, the only one where you should kill the small one first is Krugs. The little one deals about 75% the damage of the big one but has less than half the health.

For single target clearers, you'll want to clear the small Raptors and Krugs first every time to save yourself a ton of unnecessary damage.

It depends. If you're playing someone like Zac or Evelyn who has AoE, (like the sir down there said) you can usually leave the AoE to slowly kill smaller monsters (especially in the raptor camp) and focus on the larger one. However, if you use a jungler who is slower at clearing and has more direct ability focus or auto attack oriented, like Nautilus, you should quickly kill the small raptors first as they do a lot of damage added together. If you're doing the Krug camp (the rocks), you should focus on the large one, and maybe smite it if you want to help cc the small one. Doing any of the buffs, you always focus on the actual buff and not the two smaller monsters, unless you're Kha'Zix in which case, you'd want to get rid of the smaller ones to do more damage with your isolation on Q. In the wolf camp, I usually choose to kill one of the small wolves first, then the large on and then the last small one. I think Riot posted a thread that actually talked about how to jungle efficiently. //edit: http://boards.na.leagueoflegends.com/en/c/tips-tricks/ER5sX6rm-the-climb-optimizing-your-jungle-clear
