Furion is the One True Pusher of Dota. All others are hybrids. I acknowledge that there are other ways to play Furion, but this guide is focused on pushing.


Starting Items:
Ring of Basilisk
Tango Of Essification

Skill Build:
1.Sprout (in case things get hairy)
2.Force of Nature
3.Force of Nature
4.Teleportation
5.Force of Nature
6.Wrath of Nature
7.Force of Nature
8-25. It doesn't matter, but I generally get sprout first to help in team battles


Early Game
First, let's go over some basics. Can a level 7 hero kill an entire creep wave? Of course not. Furion can summon entire creep waves at level seven. Therefore, in any 1v1 situation he will lose.
What?
Yeah, you heard me right, Furion WILL LOSE. that is because two of Furion's skills are useless in a direct battle. So don't fight a hero without any items.

Now then. start of game, block creeps, lane, last hit deny, blah blah blah. Despite common sense, don't use any skills unless you have to.
THIS IS IMPORTANT
You MUST be level 3 in 4 minutes. That is when the first seige engine is spawned. Try to be close to your tower when the siege wave starts fighting.

Pushing a Tower in 5 Minutes
Summon treeants. Attack move them to right behind the tower. You will stay in back and provide fire support and devotion aura. Fight, summon treeants again. Make sure to kill all the enemy wave or the catapult/glave thrower will attack the remainder and totally screw up your push. Attack move them to right behind the tower(again). This time you will be at the enemy tower. If you do this right, at the exact moment all your creeps die out, the creep wave that was spawned will come into range of the tower and the tower will start hitting them. You should have enough mana to summon more treeants. Attack move them to right behind the tower.(again again). The tower is now dead.

Here's a quick bit of trivia. Did you know that a tier one tower is the equivalent of a level 11-13 hero?

With the money from your tower kill, Tele home and go buy a Nathrezim Buckler. Go back to your lane and don't die. When another seige wave has been summoned, tele to another lane and kill another tower.

At the end of 15 minutes, all enemy tier two towers MUST BE DEAD.

Mid Game
Mid game is annoying for me, because I am antisocial. Anyway, the goal now is to kill the barracks of one of the sides of the base. You now have the mana to be drowning your enemies in a sea of creeps, but if you fight them one on one you will die horribly. Thus, you must convince your team to push together with you. Bring your team with you. BRING YOUR TEAM WITH YOU.
bring your team with you.
But mister bloody knuckles sir, my team killed my cute puppy!
I don't care, just BRING YOUR TEAM WITH YOU.
Then you will have enough firepower to take down a tier two tower. They will retreat to their base when they see that you are bring teh pwnage creep wave of doom. Thus they will let you kill the tier two tower. Rinse and repeat. If you did this right, around 20 minutes into the game all non-base enemy towers will be dead. You will almost definitely have more towers than that, so the enemy will have to spend time and mana repelling creep wave. Then, with your ENTIRE TEAM (I cannot stress the importance enough), destroy a base tower and barracks when they are distracted.

You MUST do this by 30 minutes. Thus you will have giant creeps on one lane. Think, even level 25 heroes have trouble with giant creep waves, how will they defend now?

End Game
Not much to say here. Push down another side, then win.

A note on using wrath of nature:
Personally this crap nuke irritates the crap (lol) out of me, but it is good at getting kills. I'm just not good at it. Anyway... The let your creeps come into contact the enemy, then when you can see your enemy in the waaaay back, cast it at the first creep. Then it will bounce back to him and deal some damage and then you can kill him.

End Notes:
Any good sugestions will be appreciated. Sarcasm and critiscm too, constructive or not.
