I give you an absolutely +1 on the Bastard sword … dont know why this iconic weapon isnt in the game yet.
Some more:
Halberd – mix between Spear and Axe!
Musket – as new range weapon.
Claws – perfect for rending, give them multiple attacks like werewolves.
and most for all: Scythe! I want to see some undead reaper with scythes and I wanna use this 2h weapon so bad! :D
