I almost hate to post this, because the build does so well, but here goes...
The Rook I play is a flag holding stud with DG killability at mid levels. I guess he is simular to many Rook builds, but there are some esoteric refinements that put him above the herd.
Strategy: Never fight more than one of these DGs in a match with Rook: Regulus, Torch Bearer, Occulus... Any one is fine, but 2 can easily beat yer ass... Other than that, Use your towers as ground holders, and your shoulder attacks as your main offense. Boulder roll as much as mana allows and slam their asses at level 9. At level 9 you should have a tower farm in one of their portal areas, regardless of tower strength.
Favor: There is only one favor item that a rook should take if he wants to be a super stud... That, of course, is the Vial. The ability to heal 33% consistantly gives you the constitution to win any battle of attrition and to save your own ass countless times.
Equipment: (I don't mention TPs, locks etc)
Starting.... Scaled and (insert name of the 500 +5 armor here). You should be able to last at least to level 5 and probably to level 8 on your FIRST SHOP. You will eventually lose ground because everyone else has gone back to shop, but you have gained max levels and gold since the start.
Next... Both Vlemish and Plenor... Now this is counterintuative to most Rook strategies, which focus on health before mana, but with the Vial, you can play a back seat if you need to and you will have all the towers/boulders/slams you need to whoop arse.
Then... All the health you can stack. Period.
Skills:
1. PoT
2. Shoulder Arrows
3. Save
4. PoT II
5. Shoulder Tower and Boulder
6. Slam
7. PoT III
8. Shoulder Treb
9. Slam II
10. PoT IV
11+... Use your judgement as to how the game is going.
I'm tired of typing and not playing.... See you on the field!!!
