Buriza and changes to Scoundrel

I’m pretty sure I knew the answer to this but can’t recall. My question is can the Scoundrel make use of the Buriza pierce effect and can the chance to freeze proc on the weapon activate with Scoundrel attacks? I ask because RnGesus has given me about 6 of them so far this season. I think it might be trying to get me to use the weapon.
:grin:

I’m pretty sure he can trigger the proc on Windforce.
