I've been mastering a game of MERP where my PCs didn't take much care about protecting themselves and attacked at full force each round, only subtracting the Defensive Bonus from their shields from the incoming attacks. But recently a player decided to be more careful and using part of his Offensive Bonus to block incoming damage (the rules state that before you declare your attack you can subtract part of the OB of your attack to increase your DB for the next attack you receive).
This is not a problem when the PC is using a shield (usually a +25DB) and a weapon, but one of them uses two weapons in combat and asked how it would work for him.
As MERP rules don't specify anything about the two weapon combat style (in fact we had to go to the rolemaster fantasy rules in order to make his character sheet) we had to check the rolemaster rulebook again and got confused in case he decides to block/parry. This is a extract of what rolemaster rules state about parrying:
A defender may parry one melee attack each combat round by switching any or all of his OB (with the melee weapon he is using) to DB.[...]
If a combatant elects to parry with a weapon with his entire OB, he receives the "shield" bonus for his weapon. These bonuses are listed on the Defensive Capabilities Table T-3.6 (p.214).
The table adds +5 when using full OB to parry.
And this is what rolemaster rules state about two weapon combat:
Parrying: The user must reduce both weapon OBs by the same amount (i.e., the amount of his parry). Against one opponent, the user increases his DB by the amount of his parry.
And, in order to make it more confusing, Shields & Weapons section says:
[...]In addition, when fighting with one or two weapons, one weapon may be used as a "shield", but may not be used for an attack in the same round.
The main difference between blocking and parrying is that I can only parry attacks from the enemy I'm facing and still attack but Blocking can be used for any incoming attack. So, what I've leart and I want to learn is:
When wielding two weapons I need to use both of them to parry and both of them would be affected by the decrease of OB. But how is my DB increased? The same amount I subtracted from each or the sum of them?
I remember having read the first option is right, but I can't find it anymore.
Why would I use a shield if a second weapon can be used as one? And what bonus would it have if I decided to do it so: the normal shield DB or the OB plus the additional bonus of using full OB?
When using Shield & Weapon can I use my weapon as a shield? Would it count as having two shields and sum the DB of both?
