Hi, this is my first real build and it's for a lane Lee Sin. I really like Lee because he can dish out the pain early on but just completely kills everything in his path late game. Please try the build before you comment and rate. Thanks :D

Pros:
Deals a bunch of damage early.
Great harass.
Melts through minion waves late game with Tempest.
Seven abilities :D
Can hit opponents into team with Dragon's Rage.
Complete tank late game and melts through enemy health.
Really fun to play when you get the hang of the skill shot Sonic Wave.

Cons:
Susceptible to ganks and CC early.
Skill shot hits minions if not aimed right making it useless.
Ultimate can hit your opponent to safety.
He can't see.... :D

Runes are based off of early game desolation which is where Lee is weakest and a bit of late game bonus as well.
Greater Mark of Attack Damage For the extra AD.
Greater Seal of Attack Speed To make that extra attack damage hit more.
Greater Glyph of Scaling Attack Damage Just to get that boost late game.
Greater Quintessence of Desolation To get all the attack damage through to the enemy.

for masteries I take 21/9/0 making sure to get the armor penetration and damage boosts along with a bit of defense for those ganks that are sure to come if you play too well :D

Lee sin is all about the minion kills. Early on make sure to chase away your opponent s you can farm. Mid game you will want to use Tempest followed by cripple to melt through the waves. Late game use the same strategy but now it will be much more effective.

I choose heal and flash as summoner spells. Heal because you are a tank and flash because Lee is one of those people who has no way to run or in some cases if you miss that sonic wave and need to finish up a kill. Late game heal can help you tank that last turret and flash can help you get that kill just before they get on the summoner platform.




Also viable:

To finish off those enemy laners early game
If you jungle or to steal baron or dragon.
For team-fights.
Just in case they have hard CC.

What NOT to get:

Doesn't do any better than flash.
Cool-down is way too long.
No mana = No clarity
Leave it to the supports.
Again leave it too someone else.
