Curretly Calvinism has a modifier that makes their battle dice stationary due to the religion modifier "Everything is Preordained".
Predestination, and not Preordaination, is a central doctrine in Calvinism.
It's viewed as God's eternal sovereign decree, "the eternal decree of god" (Institutes of the Christian Religion, B. 3, ch. 21); placing predestination withing the the doctrine of salvation, giving "comfort, humility, assurance" when correctly teached, but he warns against "idle curiosity" or "abusive speculation".
Calvin's works were life changing in Switzerland, and the Christian World.
And he even talks about war (the concept of predestination is being used in it):
“For even wars are lawful, when undertaken to restrain the fury of the wicked, to succor the oppressed, and to restore tranquillity."
(Institutes, 4.20.11);
“Private men are not permitted to take up arms, but magistrates, to whom the sword is committed, may lawfully do so.”
(Institutes, 4.20.10–11) @compact nexus: "I think Calvinists shouldn't have sellswords because of this."
“Let princes not be rash in entering war, nor carried away by passion, nor let them employ any craft or cruelty.”
(Institutes, 4.20.12)
“The Lord alone gives peace; therefore, though they fight, it is He who gives success.”
(Institutes, 4.20.13)
Calvin warns people to not be hasty onto violence, and "tranquility" is viewed as a more christian means to life.
In no place is this referenced in the modifier for war in-game. Instead we have a stationary dice that doesn't produce "fun" as a game mechanic.
