Prepare a list of actions verb! Group the same/similar together... so you won't use 'kick' a thousand times.
stuff like swirl, twirl, turn, twist... that is one group since they are quite similar.
Punch, jab, blow, slap... could be one group of hand attack, though their clenching of fingers might be different.
Thesaurus is very helpful, there is quite a few online thesaurus resource.

I am working on one approach to satisfy my flashy description is by summarizing the details during the short pause or during the boring repetitive slashing of swords either through fighter's inner thought or bystander's whisper/thought.
Then I would avoid using too many of the same verbs, yet also give reader short while to slow down reading, and ultimately satisfy my ultra description details.
