I find this weapon to be a bit underwhelming compared to the other DLC weapons. It's not a bad weapon, but it just doesn't stand out too much in its abilities. For example, the transformed version looks like a giant spiked mace, but it has weak stun ability for some reason, seemingly no better than the one handed version. Mid-to-large size enemies barely flinch when you hit them with it. The only exception is the downward slam attacks, but those only start on your third R1 which can be hard to find an opening for. It has a bit of a weird swing arc, one that covers more area on your left than your right. The charged R2 has a bit of AoE at the end of it, but charges slower than almost all other weapons. The L2 is basically a worse version of the Kos Parasite's L2 because it causes frenzy to yourself, meaning to use it you either have to waste a rune slot for increased frenzy resist or you have to limit yourself to certain fashion options with high frenzy resist. The transform attack also causes damage to you. These drawbacks would make sense if it did a lot of damage or something, but the damage is just OK. I will say that I found it to be the best weapon for fighting Ludwig just because the weird angles and such tend to hit him more easily than other weapons. Other than that, it's a pretty average weapon.
