According to the leaked Rulebook page.Force weapons come in three categories.
Read the paragraph above the Chart
1.Force Sword AP3, strength as user,Melee,Force Weapon
2.Force Axe AP2, +1 strength, Unwieldy,Melee,Force Weapon
3.Force Stave AP4, +2 strength,Concussive force,Melee,Force Weapon
Nemesis Force Sword = Force Sword + Nemesis Rules
Nemesis Halberd = Force Axe + Nemesis Rules
Nemesis Warding Stave = Force stave + Nemesis Rules
Nemesis Falchions = Force Sword + Nemesis Rules
Nemesis Daemon Hammer = Force Sword + Thunder Hammer + Nemesis Rules
Just wanted to highlight that Grey Knights with Halberds are S5, AP2, I6, befor fireing up "Hammer Hand" AND with "Might of Titan"
I6,S7,AP2,+2D6 That is killer,while the standard Nemesis Sword becomes rightly weaker.A more balanced trade-off as far as I'm concerned (excluding GK hate)...it makes you more likely as a GK player to use the more expensive entries and thus reduce the numbers in the army in general?
