As an amateur in battle scenes, I recommend giving a perspective from both sides of the conflict. Since you're writing in 3rd person, this is far easier.

Let's say Ruby vs Jaune.

Ruby would most likely utterly own Jaune. As Jaune is in the losing side, focus on his perspective. Once a retaliation occurs, then check on what Ruby thinks about that.

Jaune blocked as Ruby swung her crimson scythe at him. Though his aura was low, he has to win this fight. There is no other alternative.

Then, for a split second, he saw it. The opening he needed.

As Ruby delivers what appears to be a decisive blow, Jaune flashed, his aura unleashing it's full potential.

As he makes use of Ruby's confusion, he apologized "Sorry, Ruby!" and swung his blade with all his might, knocking Ruby back.

Ruby looked on as Jaune radiated a shimmering white glow. ''It took several months, but Jaune finally did it. Congratulations! ''Ruby thought, happy that his friend finally controlled his hidden potential. She took out her previous ammo magazine, replacing it with the Cross Shot. This time, she doesn't need to hold back.

"Sorry, Jaune! I can't let you win either!" she said, holding the trigger to her scythe.

Only one of them has to win. There is no other alternative.

And that's an example. Visualize and describe it. It's like a super-elaborate wordless conversation. Lots of actions, almost no talking. Mostly.
