Some are spawned during the game via event script, so there is no natural spawn chance.

Considering that some event spawned systems require a lot of additional setup to work as intended it unfortunately isn't as easy as just adding a spawn chance to them. There really isn't an easy solution that fits everything here.

That's too bad, but thanks for the answer anyways

You might also be thinking about usage_odds and not spawn_chance

spawn_chance defaults to 100% but used to decrease probability of spawn. Most would be scaled_spawn_chance which is multipled by number of stars/100

Hi, sorry to hijack this, but do you by chance know is there's a way to check if the Luminous Flame system has spawned in my galaxy upon starting a run?
