I can't agree with that... Based on my own gaming experience, I can say that it is often possible to repeat the damage of a unit attacking an opponent when replaying the battle... It's difficult to say how a particular moment is determined (I personally can't :)), but I think that the core of the game has a certain system that simply repeats itself over time...
Highly doubtful :) Damage is random within a range, and it is impossible to repeat it consciously... We are not talking about a random coincidence - this sometimes happens. But the conversation is about whether it is possible to achieve 100% repeatability of its behavior. I think not.
Here's a question of this kind:
how does the clone spell behave? I mean, what is its duration?...
P.S. I just came across a discussion about this, and I referred to spall power, but is that really the case? - I want to know...
Also: what types of spells last throughout the battle, regardless of the spell's power? (for example, like destructive ray...)
