Some advice on a good build for an orc? Preferably melee advice though, since hes a warhammer user.
Here's a fairly straight-forward build that focuses on almost all of the Orc's primary and secondary skills; it's also a build that I have personally used successfully throughout the game so far:
Health/Stamina: 50/50
Heavy Armor: Juggernaut 1-5/ Well-Fitted/ Tower of Strength/ Matching Set
Two Handed: Barbarian 1-5/ Champion's Stance/ Devastating Blow (it works with Warhammers)
Archery: Overdraw 1-5/ Eagle Eye/ Power Shot
Smithing: Steel Smithing/ Dwarven Smithing/ Orcish Smithing (Optional: Ebony Smithing/ Daedric Smithing/ Arcane Blacksmith)
Enchanting: Enchanter 1-5/ Insightful Enchanter/ Corpus Enchanter/ Extra Effect
Optional Tips:
Get the Warrior Standing Stone first; later in the game when you have most of your desired Warrior Tree perks, switch to the Lord Stone for the 25% Magic Resistance, or the Atronach Stone for the 50% Spell Absorption. Also, do the Mara Quest asap to get an easy 15% Magic Resistance, since magical damage will be one of your Orc's few weaknesses.
