Hello,this is my first time i am making a guide-build i hope you like it and helped you aswell.
Pros / Cons
1)Nice Passive,it can finish off an enemy if they are too low and trying to escape
2)For this tanky build Darius has descent damage done because of his "Q"
3)If played well there is no escape for the enemy(slow+pull them back)
4)Legendary ulti for true damage and refresh of its cooldown if you kill your target with it
1)Pretty weak damage if you are failing with "Q"
2)Diffycult to master him
3)Not mana escape methods
If the enemy team has more AD than AP then i would suggest you to purchase thornmailinstead of force of nature
Healand flash is a great combination for Darius because since you are the tank of your team you need a heal for the critical moments and everyone knows that flash can help you escape(since Darius has no escape methods) and also it will help you pull the enemy at you if you use a good rotation and take advantage of your flash
Thats the end of my guide i know its not too big since its my first time i think its a nice excuse xD.If this guide helped you please vote up if not please make a comment and make suggestion .
