For an order of discreet assassins, the Shadow Wolves certainly have a tendency for charging headlong towards a target, all the while screaming war cries. Once they reach it, they then comically dispatch said target with one of the biggest halberds in Pendor.
The Shadow Wolf Halberd is both large and powerful, and among the best polearms in the game outside Rune Weapons. Being that it is only used by the Shadow Wolf himself, it is also difficult to acquire. One can rarely find this in merchant shops, but hunting down packs of the Wolves and searching their loot is propably a better option.
