On p. 129 of the Core Rulebook, it's stated: "There are advantages and disadvantages to this style of fighting." However, unless I read between the lines, disadvantages are not easy to see.
Basically, there may be never a reason not use something in your off hand while fighting (unless you can't afford it or missing an arm). You can continue to fight as normal using your main weapon, but you get a free parry each round because of your off hand item!
I'm not specifically looking at encumberance as being the balancing rule. As a seasoned GM of WFRP 2e I've hypothesized a few disadvantages. These are not explicitly stated in the rules that I can find:
- Limits Attacks. In the example where the PC may have two pistols, only two attacks are possible. PCs with 3 Attacks would be limited to 2 Attacks (even with Swift Attack). This applies to two weapon fighting as well, if choosing to use the weapons as stated.
- The Free Parry is Penalized. As I read the rules, at -20% WS in an off-handed test. Where as entering the Parrying Stance would not be penalized, but also cost a half action AND prevent multiple attacks.
- All Out Attack with Two Weapon Fighting costs the free parry.
No question that room for abuse exists. Is there something in the rules I've missed or is it necessary to house rule the detail.
