Hello, this is my first build. I like to play as Tresh and i decided to create a guide for myself and others who likes to play this way. And yeah my english sucks, sorry for that :)

This build is still under construction

•Tresh has got a great passive. You won't even need armor or AP items.
•You can play as tank, ad carry or support.
•Fun to play.
•You can save your friends in bad situations.
•Most important: Almost immortal when you choose tanky items.

PROS

• Easy to farm.
• Hard to die.
• Very good passive.
• Death Sentence spell makes you a TF starter :)
• Ranged and tank.
• Can support teammates.

CONS

• Easy to die in early game.
• Hard to pull enemy with Q in lanes.
• Some people doesn't know how Dark Passage works.
• Pantheon's passive blocks your first attacks.

Ignite Tresh hasn't got poison, burn etc. effects so we need to know our enemy didn't escape with 100- health.
FlashFor escaping from bad situations.

Heal Can be good for more support.
Exhaust Good for 1v1, worst for TF

Berserker's Greaves For early attack speed. Better than Mercury in my opinion.
Statikk Shiv Tresh's Q makes this item the best for him. Move around until stack 100, make sure your Death Sentence looks red. Attack someone and see how high you hit them. Also can be used against big creeps.
Frozen Mallet A good health source also helps chasing with freeze.
Wit's End Passive: You can use your AP(comes from passive spell) with autoattacks thanks to this item. And it has a good attack speed.

If You Need More Health: Warmog's Armor

If You Need Magic Resist Against Champions Like Nidalee: Spirit Visage

If there's too many cc'er in enemy team: Zephyr

IF You're winning and you want to have more kills: Runaan's Hurricane

For Life Steal: Blade of the Ruined King

Your first attack gains power from your Death Sentence. When you wait without autoattacking someone, you'll see the small picture of your Death Sentence turns Red from green. That means you will have the stronger autoattack when you hit first.

Now I hope you get why I choose statikk shiv.

When you move around, this item stacks up to 100. And when that happens if you autoattack someone,the electricity makes your attack powerful and multi-targetted.

When you autoattack with your full Q and stacked statikk shiv, that means you will hit almost 3x and to 4 targets.
