The stats that this site gives as a result of my build are incorrect. Frankly, I find this site to be incompetent, because it is significantly inaccurate. For example, my damage actually should be 376, my attack speed 1.896, my movement speed 467, etc. So, do not pay any attention to the stats at the top.

I am only willing to spend 5 minutes making this guide, so I'll keep it to the point.

I dominate mid lane every match I play with this pantheon build.
I humiliate any and every mid. You name it, I've killed it.
I excessively play pantheon, and I've used him in 80% of all my games.
My build is costly, but when games last a long time, I am always the first with full build due to how effective my system is.

Phase 1 of my item build is:
1. doran blade
2. mercury treads
3. doran blade
4. doran blade
5. doran blade
6. zeal

From this point, I build towards this phase 2:
1. doran blade
2. mercury treads
3. trinity force
4. bloodthirster
5. doran blade
6. zeal

From this point, I gravitate to my final build which is again:
1. mercury treads
2. trinity force
3. phantom dancer
4. bloodthirster
5. bloodthirster
6. madred's bloodrazor

My starting items, in combination with runes and masteries, makes my debut mid laning phase ungodly effective. Throwing a spear every 3-4 seconds with massive dmg at only 45 mana cost, hop-stunning with my w whenever the enemy mid even thinks he is allowed near the minions, blocking with innate, and never wasting mana or ability upgrades on hearseaker makes this strategy undefendable.

I give the enemy two options:
1. die now
2. or die later

It they decide to use an ability against you, they will be met with far more damage as retaliation - spear shot, hop-stun, hit, spear shot

So if they are wise, they'll choose die later.

It is hard to not be arrogant when you play as pantheon
