Paragon Riktor Hook Animation

Hi There!
I have been trying to recreate Riktor’s Riplash ability (Hook Pull) from Paragon.
I have some problems regarding the animation and how to implement it. Since I have different animations( one for casting the ability and another with the moving chain), how can I merge/combine these two to make the chain come out of the character’s arm. I have been trying to use montages and layered blend per bone but without success.
I have uploaded two gifs with the respective animations and Riktor’s Overview Paragon youtube video in case you want to check how the ability works.

Thanks in advance!

Did you manage to do it? I got the tip of the hook expanding from his hand using an additive animation, but there is no chain or flames. Really beating my head against the wall with this. I’m not takign player input as I’m looking to give this ability to ai.

I managed to get something close for what I need with a Layered Blend per bone between the Hook Cast animation and the Hook Throw animation targeting lowerarm_twist_01_r. The hook tip wobbles around but I can work with what I’ve got.
