What it says in the topic title, really. It seems like force weapons are all conversions of their primitive weapon counterparts - rod, scythe, staff, all match damage and pen exactly. In fact, in the force description it states that "any primitive weapon can be made into a Force weapon, and increases its Availability to Extremely Rare" - implying straight conversion, just adding Force keyword.
It then describes how you get +1 to damage and pen for each point of psy rating you have. It even gives the example that a Force sword wielded by a person of psy rating 3 would inflict 10+3 (plus SB) and have a Penetration of 3.
All of that is quite clear. However, in the table of melee weapons, it lists the Force Sword as 1d10+2 R damage, 2 Pen. Why is this? Regular sword is 1d10, 0 Pen. Following the example in the Force keyword description, the psy rating 3 person using a force sword would do 1d10+5 damage, 5 pen.
Is a "Force Sword" different than a "Force sword"? Seems erroneous to me. Where'd that bonus +2 come from, and why?
Side question - Force description states that the force weapons become extremely rare, but all force weapons on the table are listed as near unique. Which is correct?
