Saw some people wondering where it was. It's an easily missable piece of equipment and it looks like an ordinary sword unless you examine it at which point it becomes a unique weapon.

 

I added some pics for people to find it.

Been my mainstay weapon throughout the campaign, dual wielded with magistrates cudgel.

Kinda wish the blade had more of a story to it though - and a few more upgrades to it.

 

Yeah, I'm currently using it one-handed style. It looks epic, especially for ciphers!

Coolest sword in the game for me.

Although I modded it to add a few more abilities to be usefull throughout the game when comparing with all other unique swords.
