I tried looking for the LN and cant find it I guess I wait for next chapter. can I just ask did he use rts mechanic, DND mechanic or neither cuz I want to confirm my own speculation without dulging to deeper
He used his RTS rules as well as a third rule set. Saying more would be a hard spoiler, but it’s a solution that has been set up a VERY long time ago.
You can buy the official release of the light novel, it’s past this arc and worth supporting.
