I seem to keep dying to monsters in jungle with lee sin, Im level 23 and I've watched tons of videos and guides. please help

Lol? Do you have runes, masteries, etc?

Focus on getting armor seals, they make it A LOT easier.

i recommend starting cloth armor 5 health pots then go wraiths-->red--->golem-->wolves--->blue or u can gank in between it

Armor pen marks
Armor yellows
Mg resist blues
Mv speed quints
^ my rune pages.

Start cloth 5 and go to wraiths, get some damage on wraiths then a leash on red. From there is usually go wolves, wraiths, golem.
Get your E first, remember to use your passive, E > aa, aa> E
Then get W after wraiths. Then Q at three.

I usually don't get blue buff until after I B and get boots.

you could try looking up builds that appear decent, such as solomid.net or mobafire.com

Getting armor yellows is a must, level e w q e w, wraiths red then wolves. Constantly use your abilities while clearing. For masteries go 21 9 0, start cloth + 5, machete + 5 in s3.

go full defense, even if lee is usually a 21/9/0 champ, you should go 9/14 since you are not level 30 and dont have full masteries and runes

7 Armor pen marks
7 flat armor seals
7 scaling MR glyphs
2 AD quints

Masteries Offense
2/3 Brute Force
2/2 Butcher
4/4 Alacricy
1/1 Weapon Expertise

Defense
1/1 Summoner's Resolve
3/3 Hardiness
2/2 Tough Skin
4/4 Durability
2/2 Indomitable
1/1 Veteran's Scars
1/1 Bladed Armor

This should allow you to jungle without getting killed by minions, start with a cloth 5 and remember to shield yourself and use the lifesteal and spellvamp from your W, going W W E should allow you to take a lot less damage from each camp.

And get a leash for the first red ofc.

Good on you for trying jungle, does the lower level meta normally have jungle? I never really saw it below 28 partly because inexperience in the game makes you a better Laner than jungling and the whole runes and masteries can put you at a severe disadvantage. Idk i was always told to not try and learn jungle till i was close to thirty.

lee sin is not a good jungler he is never played after 1k elo. lulu jungle is much stronger and she rarely dies from minions
