There are multiple starter post about sampires in the warrior forum.
Honestly, for a sampire when you break it down all you need is a weapon skill, tactics and necromancy. Everything else is about flavor and what you want.

Chivalry- similar to Bushido but can be cut out more often because not as essential as Bushido in effectiveness.
Anatomy is probably the most commonly swapped out skill for Resisting Spells.
I've seen and used builds with Spellweaving, Bard/Discord....
