Hidden blade materials

Was wondering if anyone could post the mats on hidden blade

I’m pretty sure that the only way to make a hidden blade is trading in a lvl 30 Zaj bow to one of the two gamemaster npcs (I forget which one) that spawn during the anniversary event in July. If you have a 30 Zaj bow, you can ask Zaj to spawn it when he’s on. I don’t remember if you need any other mats UT if you do, I don’t believe it’s too tough.

I think you also need 5 gm souls and 2k frags. It’s expensive but it’s a good weapon
