Hey :)
With my first words I want to say that my english isnt really good.
I hope you understand what i want to tell you about my perfect way to play Sejuani.

Like all the other Characters there are many ways to play Sejuani.
But one fact comes clear out when you play her.

She can perfect rush in and start the teamfight.

When you and your team make it really good Sejuani starts and ends the teamfight within 3 seconds.
And on this fact I set my focus with this built.

Since many games i work on this built to make her to the best Initiator ingame.
Since many games i work with this built and i really can say i never was dissapointed about me or Sejuani even if we lost the game.

Why I decide to make this guide?
- When i start playing Sejuani I follow my ways to the Top rated guide here.
I played with it but I never was pleased with it.
in my eyes Sejuani doesnt need AP.
In my eyes Sejuani need durability to set her CC and with her huge life she automatically does damage with her W Spell.

For Runes I pick

Magic penetration
for balancing a little bit her 0 AP in the whole game.
especially in early game ganks this magic penetration will be useful like gold.

Armor
I think i dont have to say much about armor.
For jungle and for ganks on bot and early tower dives.

Scaling magic resist
as tank mr is of course important but you dont need magic resist in early game.
Till level 6 the ap carry cant do much on you and the supp on bot will never be a danger point for you.

For masteries I set the most points in the tank tree.
Early game durabilty for easy jungling.
Little late game support for your tank role.

I took a long time for the last 4 points.
I decided that more movement speed while doesnt fighing to come faster trought the jungle is the perfect choice.
The last point was the most difficult. But at the end i decided that this point would be better to come one second faster back while low life or when you get chased instead of
good hands. As tank you`ll actueally dont die at late game when fast come back is necessary.

I dont have to explain much for the items. Huge life, really huge armor and huge magic resist to give her really high durability.
With this items you have a active time between 6 - 10 seconds when you rushed in enemies and they fight against you 5 v 1.
This is obviously not the way like your team have to act.
The best way is when follow you in teamfight after 1 second.

From the beginning since I played Sejuani I maxed the W spell for the jungle.
Obviously the best way.
But in my newbie days i maxed as second spell Q.
This is completly wrong and you have to do it like i wrote it down.
The massive CC of your E is your most POWERFUL weapon on ganks.

The summoner spells are my most weak point.
i took smite for jungling and flash as unique spell for unique situations.
You can swap flash with every spell you prefer.

All - in - all
Your Job with this built is to rush in first
hit so many opposites with your ult as you can
and control your main focus with your cc.

in short way.
1. You rush in with full life.
2. get focused spree your cc.
3. come out as hero with max lost half 3/4 life.

I hope you try my Guide and i really hope you like it so much as i like it.
I really love this way of playing Sejuani.

Pls give me Feedback for work on this Built and pls not to work on my english skills :)

Thank You,
