Sure you're more than welcome to play a warrior from Gondor. Any of the men from Arnor or Gondor are open as options.

I don't really understand how body development rank bonus works... are you supposed to roll d10 for each rank?

Yes, you roll 1d10 per rank.

K, thanks

Np.

I can't find anything about armor and hit points in the rulebook. Anyone can help?

Heavier armor allows you to shrug off more crits but slows you down on your movement maneuvers. You really see how armor protects on the crit tables. Your hit points basically are covered during character creation and any ranks in Body Development add to them.

Your hit points is the d10 per rank in body development plus your Con bonus etc. Armor basically protects you from criticals/reduces the amount of damage the heavier the armor with chain/plate being the best. You'll get hit more often, but it will be minor compared to being hit in leather. Remember to consider a good defensive bonus as it reduces an opponents to hit roll and in turn reduces the damage you'll sustain no matter what type of armor you wear.

Combat:
GM Determine surprise
Roll initiative
Make any MM/SM needed to get within melee or range.

Open ended d100+Opponent's OB - Your DB = result compared vs armor type/weapon type on combat chart

Same method applies to your own attacks vs an opponent.

The bonus for having a shield is very nice.

Thanks a lot for the clearing
