How to Invoke a Guardian Beam/ Guardian Attack Speed

I was wondering how to increase the rate at which the guardian(non-elder) beam effect plays out. Such as increasing the time it takes from once the beam starts to the time it ends and hurts the player. My other option would be to create a beam if the above cannot work, then damage the player when the beam animation ends.

I'am not sure if ProtocolLib can do this or is a good option for this as i am new to the idea of NMS.

 

I'd be going the NMS route.

Most likely setting custom PathFinderGoals or setting the entity's target

 

I don't necessarily need to set the target, I need to essentially speed up the attack of the guardian. PathFinderGoals to me sounds like you are defining a path or some sort of target like you were saying, if not, perhaps you have a good tutorial?
