Q.1. Could you please build me a 8th level gestalt warlock/paladin of tyranny?
Books: almost everything but setting books

Race: I was thinking in human necropolitan
Ability Scores: 15,15,14,14,12
Alignment: lawful -evil
House Rules: My DM says magic items will be available for purchase but we’re not building them ourselves, so avoid item creation feats.
Concept: I’m thinking of a quiet, not flashy, but still effective caster. A real team player.
Other: He is going to be the stereotypical death knight in night black armor, I am mostly worried about feats but I wanted to use hidous blow to increase damage output but it works as a stantard action, is there any way to use it as a full round action like the duskblades do with spells?
I also think it will need battle caster to use heavier armor and the warlock powers am I am going to take fell flight, so fly by attack or other feats might be interesting.
