Critical Bug with Whirling Blades (Not a bug - resolved)

Critical bug with Whirling Blades. In the description :

"

"Dive through enemies, dealing weapon damage. Only works with daggers, claws and one handed swords."

At the moment, the skill works with bug - it does not work with Gemstone Sword. Doesn't work with any one-handed sword. I can use claws, claws + blades. But when I pick up a one-handed sword, it refuses to work. In any state, with or without gems, in any combination.

For me this is critical - I bought the good weapon... Fix it plz! Or tell me what is wrong with me!

Not a bug.

Thank you!
