Hello guys and girls,
this is my first guide so it might not make much sense and i'm still figuring out how it works.
So please give some feedback to help me improve making guides.

I don't want to make a guide you have to read in an hour, but just a quick guide so you know what to buy etc.

In my opinion these are the best runes, but if you want to jungle easier you should take Greater mark of Attack Damage instead

Standard offensive masteries
When jungling I don't like to take the less damage from neutral minions because it's quite useless as soon as you go back to shop for the first time.

If you don't like Statikk Shiv you can replace it for Wit's End but you need some kind of attack speed and the crit on Statikk Shiv is also very nice.

I think Blade of the Ruined King is very good with the attack speed you already have, the attack speed of Denting Blows and the attack speed of your Statikk Shiv/ Wit's End but if you do prefer the extra AD and Lifesteal of Bloodthirster you can pick it as well.

When you jungle and play against a heavy CC team, you can change Statikk Shiv for a Zephyr for the tenacity, if you play top you have tenacity from Mercury's Treads

Solo Top

Cease and Desist your ult should be obviously taken whenever available
Relentless Force is your main burst, harrass and farming spell and should be maxed immideately
Denting Blows is great for 1v1 fights, tank fights and for jungle creeps
Vault Breaker is your gap closer and should be maxed last, it's only for initiating.

Jungle

You should start with Denting Blows for the %hp damage and the attack speed.
Don't start with Relentless Force because the cooldown for stacking them up is way too long

Pros

Great initiation
Great farmer
Great burst damage
Fun to play

Cons

You'll be focused because you deal tons of damage
You need to hit vault breaker when ganking or the gank has failed

Let your team help you with wolves and blue buff, then take wraiths, golems, red and wraiths again.
When you're above half health you can gank a lane, else you should go back and gank.

Initiate with Vault Breaker Note: If it doesn't hit, back off
Use 1 auto attack and immideately after Relentless Force because it resets the auto attack timer
do this every time when right after an auto attack for maximum damage output.
Wait with using Cease and Desist until they used their escape ability OR when your opponent is about to use heavy CC to counter it.

You shouldn't be the one to initiate, let a real tank do that.
Try to hit their main damage dealer with Vault Breaker and use your combo.
If you can't hit their main damage dealer with Vault Breaker you should use Cease and Desist to close the gap and beat them to dust!
After their main dmg dealer focus the other carry and clean up the remaining enemies while using Relentless Force whenever it's possible (but still use it right after an auto attack).
