Honestly, I've always maintained that whatever RPG you play, one of the earliest 'special' weapons typically turns out to be one of the best.
Here, even if the target cannot be 'bitten, the sheer attack-power is just beastly. Combined with a longer Perseverance than other hammers and it's reach; it's just a beast. Slow, but it's got the right mix of sweeping (horizontal) and slicing (overhead/vertical) attacks too.
On the lesser side w/Str requirements so you can put those points into other things if you want to (vs 50 Str say for FUGS).
