hi, I have been playing the latest beta version of your mod for a while, and the newly added features are really great.
Below are some of my game feedback.
Jump attack:
It seems that this function can only be triggered by pressing the attack at the moment of jumping, which is a bit stiff in terms of experience.

Custom entity:
You are really awesome! You implemented this feature a long time ago! This solves the problem of mod applicability to a large extent, but a person's energy is limited, you can't make animations for other mod creatures, which is very hard.
So can there be a compromise solution to solve this problem, such as:
Add a custom setting to let the mob obtain the endurance value based on hp. It can be a very complex function or a very intuitive custom value. When the mobs are attacked, it is no longer a simple knockback but will be stunned.
That's right, just like the battle ai in your mod, it doesn't require you to spend a lot of effort to develop a set of animations, it just exists to adapt to your battle mode. In fact, some mods already have vertigo animations, such as dannys expansion and mowzies mobs.
This is great, isn't it?
Maybe this will be a great start, a new battle mode that will subvert mc.

Heavy hit
Add a heavy blow function to the weapon and add a binding key. The heavy blow may require a large amount of stamina and long-term storage to complete, of course, this process can be cancelled at any time.
Heavy hits are different from attacks and skills, and may have a powerful knockback or stun effect.
For example, the heavy blow of a giant sword may be a forward stab beyond the range of a normal attack.

Backstab
You should know what I think (haha), this may be a way to pvp.

More weapons!
My God, the attack animation is really good, I really look forward to what the next weapon will be.

If you are caught in a selection dilemma, you can initiate a vote!

I hope epic fight has a better future.

I like the idea of heavy hit. It might even come in handy with the skill tree suggestion I made.
