Common Questions
How does Luck actually work?
Luck uses a hidden reroll system. Luck 5 is baseline. Every 10 points above 5 effectively gives you more tries, and the game keeps the best result—raising real success odds.
I don’t know the base chance. Am I stuck?
No. Switch to Range mode inside the calculator. Range mode is best: it shows best- and worst-case success odds so you can make a decision without exact hidden data.
Why do events have different stat checks?
Many event choices are gated by a stat (Dex/Int/Lck…). Use “Browse by stat” to find relevant events, then compute the real odds after Luck.
What is Crit Success?
Some events have a separate crit roll for the best outcome. This tool models crit chance separately and applies Luck rerolls to it too.
