Dynamo

Dynamo does not add a weapon or an object but a new feature. This mod increases player attack damage with his kinetic energy. This mod is not 100% accurante for balancing purposes but can transform your game experience, it is no longer enough to attack with the most powerful weapon, but to be aware of its environment to do the most important damage (take height to fight and make dynamic attacks). When you run, fall or jump, your momentum will increase and allow you to do more damage.

I'm French and this mod was done with Mcreator (Sorry if I make mistakes in English 😅) 

You can gain momentum from a big fall, speed potion effect, elytra, horses... etc
