Foreword: This guide is strictly for people with good computers, reflexes and tactics. This is not for new players! Camera changing, retreating and re-engaging are critical to this build.
This is a strictly hero-killer build. It is -very- offensive. Keep that in mind. And don't knock the build without providing details on why it sucks because I've tested this build -many- times and I do very well with it.

*Picking at Level 2 is situational. If I have an open lane with no opposing Demigod I'll get Structural Transfer and start pushing the tower, otherwise I go with Arrows.
Favor Items I Use:
Blood of The Fallen *
Swift Anklet *
Saam-el's Cloak ? - only against Demigods with lots of slow abilities (Regulus & Unclean)
Staff Of Renewal ? - I can't imagine being able to Hammer Slam every 8 seconds and Boulder every ~12 seconds.
Where * means I have used them and they work good and ? means I've never used them (not enough Favor) but I think they could be good.
Items: (Bought in this order)
Unbreakable Boots
Plenor Battlecrown
Nimoth Chest Armor
Journeyman Treads
Boots of Speed
Wand of Speed
Groeffling Warplate
Heart of Life
I usually also carry Universal Gadgets, Teleport Scrolls and Capture locks.
Late game I've never needed to buy any Artifacts but Bulwark of the Ages sounds like a good fit, that or the Allfathers Ring.
As far as gameplay, Hammer Slam the very first creep wave and avoid fighting Demigods until you get level 5. Once level 5 get enough mana to Boulder/Slam and wait for the right opportunity.
Boulder/Slam combos the rest of the game.
Possible Teamups:
Unclean: Rook leads stun with Boulder and Unclean uses Foul Grasp to hold them in place for a Hammer slam.
Oak: Rook Boulder Rolls and starts his Hammer and JUST AS ITS ABOUT TO HIT Oak uses Pentinence because Pentinence INTERUPTS THE BOULDER ROLL STUN AND THEY CAN MOVE AFTERWARDS.
Vampire: Rook leads stun with Boulder and Vampire Mass Charm stuns to hold them in place for a Hammer slam. This works well if melee characters are grouping up as you can slam multiple enemies.
