Weapon groups are families of weapons that share
certain properties. They’re wielded similarly and are
equally suited to certain kinds of attacks. In game
terms, some powers and feats work only when you’re
attacking with a weapon in a specific group.
If a weapon falls into more than one group, you
can use it with powers that require a weapon from
any of its groups. For example, the halberd is both an
axe and a polearm, so you can use it with powers that
give you an additional benefit when you wield an axe
or a polearm.
