Normally it's like this.
Battle commence!
[Enemy names up to 3, extras are with some backup allies] and then insert something cool like break the void or shatter reality.
[Good guys names up to 3, with some backup allies if you want] and then insert something like return the favor or are eternal.
Battle style is where the good guys go first. You label their attacks like
[Ally 1] used [attack name]
[number] damage to [enemy name]
[enemy HP] left.
When an enemy dies, it goes [enemy name] was killed or something like that.
Do the same for each side.
At the end of a battle, it goes [battle won!] or something.
If you want, add a drop and ask the readers if they wanna keep it or discard it.
Either way, those are my tips.
