Hi guys,I'm here to share with you my Darius Guide.He is my main for a long time,and i've realy tried a lot of builds and strategies,but this one seems to work best for me.Darius is meele,tanky DPS champions who excels at 1v1 situations.

Here are some Pros and Cons for Darius:

PROS:
*High Sustain and Damage
*High Damage Ulti
*Great Team Fight Initiator
*Can Easy Get Lot Of Kills

CONS:
*Low Mobility
*Semi/item Dependable
*Focused In Team Fights
*Weak Against a Ranged Champions

OK,My runes for Darius focus on High sustain and good damage.For marks i take Armor pen.I take armor seals and magic resist glyphs and health quintessences.Armor and magic resist are for durability in lane.Armor penetration is for better damage and HP quintessences help a lot early game.This is my personal favorite rune build.

Not much to say about masteries.They focus on damage and sustain just like runes.

Darius has a high damage skills.His Decimate is AoE spell that deals decent damage to foes in a circle around Darius.I take 1 point at lvl 1 and max it first.Cripling Strike is Darius's second spell.It gives extra damage and slow to his next basic attack.I take 1 point at lvl 3(you can also take a point at lvl 2) and max it right after Decimate.Apprehend is Darius's third skill.It passively gives Darius extra armor penentration.When you activate it it pulls all enemies in a small cone back to Darius.I take a piont at lvl 2 and max it last.Noxian Guillotine is Darius's awesome ulti,and one of the best ulti in the game.It deals high true damage to a single target.It damage increase by 20% for every stack of hemmorhage on a target.Finaly Hemmorhage is Darius's passive skill,whitch inflicts bleed on a target stacking up to 5 times.It deals Damage over time.
I max Decimate first since its Darius's nuke and main damage and harass ability.I take Apprehend at lvl 2 not Cripling strike so that i can pull back running enemy champions.

I take ignite and flash for a simple reasons.Ignite in combination with your passive deals very high damage.Flash is used to chase and escape enemy champions.

Ok my build includes High damage,and high durability.I open up with a boots of speed and 3 Hp pots and upgrade it to mercury treads.Next i go for Phage and upgrading it into frozen mallet.It give you a lot of HP,some dmg and a slow to attacks.Right after that i buy B.F. Sword for more Dmg.Then i go for Warden's Mail.It adds me some good armor and HP regen.Next i go and upgrade my B.F. Sword to infinity edge.After that i finish my Randuins Omen.At this Point you have it all.High dmg,lots of health and good armor.Next i go for Atma's Impaler.It adds me more armor,More dmg and some critical strike.To Round it all up i get Warmog's armor.It adds a lot of HP and cause of Atma's you get even more DMG.
So with This items you have:
-Lot Of health
-High Armor
-High Damage
-Good HP regen
-Decent Critical Chance
What more could you want :D

This is my first guide so i would really like to see you comment.I will Update this build with more info soon.Soon i will add strategies and tips on how to play as Darius.
Until then.
