Dota 2 - Clockwerk Build Guide

BIO
Rattletrap descends from the same far-flung kindred as Sniper and Tinker, and like many of the Keen Folk, has offset his diminutive stature through the application of gadgetry and wit. The son of the son of a clockmaker, Rattletrap was many years apprenticed to that trade before war rode down from the mountains and swept the plains villages free of such innocent vocations. "Your new trade is battle," his dying father told him as the village of their ancestors lay in charred and smoking ruins.

It is a poor tradesman who blames his tools, and Rattletrap was never one to make excuses. After burying his father among the ruins of their village, he set about to transform himself into the greatest tool of warfare that any world had ever seen. He vowed to never again be caught unprepared, instead using his talents to assemble a suit of powered Clockwerk armor to make the knights of other lands look like tin cans by comparison. Now Rattletrap is alive with devices-a small but deadly warrior whose skills at ambush and destruction have risen to near-automated levels of efficiency. An artisan of death, his mechanizations make short work of the unwary, heralding a new dawn in this age of warfare. What time is it? It's Clockwerk time!

INTRODUCTION
Clockwerk has a hook to initiate a teamfight from a long range. This hook is the determiner of the teamfight. If you can make a nice hook, it will greatly help your team to gank and get many kills. So as an initiator you need to learn the hook everyday.

PROS	CONS
A long range initiating skill	Low mana pool
A global AoE skill	Need practice
Can trap enemies inside a box and beat him up	Need a good positianing
A good map control
A nice initiator
Imba ganker

2. Power Cogs

Forms a barrier of energized cogs around Clockwerk, trapping any units that are near. Enemies outside the trap that touch a cog are knocked back, losing health and mana.

4. Hookshot

STRATEGY
Early Game
Clock is a ganker, he needs a target. But before you start ganking, you need some farm to be ready to roam. Farm carefully and try not to get killed on the laning phase. last hit carefully and harass enemy once in a while. Be careful from unexpected gank from behind! Use the cog immediately to escape.
And If your opponent is accidentally in a bad position, you can use cog to trap him, and Battery Assault immediately to kill him.

Mid Game
On here, mid game, I assume that you already acquired your ultimate: Hookshot. With this skill, you will start ganking and killing. Maybe you can buy smoke of deceit to hide yourself from enemy's sight. Hook is a straight line, and if enemy move by a amall step away, it will barely missed. Count 1 2 3 and land a perfect hook. Remember to use the Power Cog after you successfully landed your hook. And after that kill your target using the Battery Assault. Cog last long so your enemy cannot move away anad constantly can be harassed by you. Your friend can also helps by clicking the target while he is trapped on the cog.

Late Game
Late game Clockwerk is one of the most fierceful ganker on the game. You land a hook, trap a target, kill him and hook another target, and kill him too.

Dota 2 - Axe Build Guide

BIO
As a grunt in the Army of Red Mist, Mogul Khan set his sights on the rank of Red Mist General. In battle after battle he proved his worth through gory deed. His rise through the ranks was helped by the fact that he never hesitated to decapitate a superior. Through the seven year Campaign of the Thousand Tarns, he distinguished himself in glorious carnage, his star of fame shining ever brighter, while the number of comrades in arms steadily dwindled. On the night of ultimate victory, Axe declared himself the new Red Mist General, and took on the ultimate title of 'Axe.' But his troops now numbered zero. Of course, many had died in battle, but a significant number had also fallen to Axe's blade. Needless to say, most soldiers now shun his leadership.
