Well, my schedule prevents me from setting a real time at the moment, but once things settle down a bit I'll post here and see if we can't arrange something.
Please do note that a hammer rook, much like many other builds, faces distinct disadvantages against some characters; for example, anyone with an intterupt can 'kill' us if they jump in. A frost TB is one of the worst nightmares I know, because I cannot get anything done unless I stun him first (and frost TB's are usually to canny to try and melee me...). One on one, I'm devestating, but once the enemy gets a group going my utility drops drasticly. (To be clear, I'm talking about it dropping even more rapidly that most DG's would in a similar situation).
On the flip side, I don't worry too much about Sedna or oak, because I can just (eventually) bash my way through shields or heals.
For anyone interested in the general idea, my build to level five usually goes...
Hammer, archer tower, <skip>, hammer, boulder + tower of light. I don't remember for sure where the next few points go, but I think it's the +dmg, hammer, then trebuchet ones, then I hold my level 9 ability to level 10 to grab another +dmg and hammer point.
I usually focus first on +HP (and HP regen is nice too), then +armor gear, with just enough mana gear (normally just the 1500G helmet) to keep me from being unable to use my abilities at all. The central core of my rook approach has always been endurance, so I focus on that until I hit artifact level, then I look at some of the +dmg items (specifically, the sword with life-leech, ashkandor I think) that help out enourmously with killing stuff.
