Looking for Unique Controlling Weapons

I had a lot of fun using the Tall Grass pike in PoE (https://pillarsofeternity.gamepedia.com/Tall_Grass), building a barbarian for max crit potential and watching groups of enemies knocked prone for the whole fight. I'm hoping I can do something similar in Deadfire.

What controlling weapons have you found so far?

No weapons, but I did buy some gloves that have a 50% chance to knock down on crit, which is very similar to Tall Grass.
