Yeah, no way are we burning through our reserves on Slice Fate.
I think that you are genuinely underestimating the value of a single reroll, here.
It turns a 10% risk into a 1% risk. It turns a 25% risk into a 6% risk. It turns a 50% risk into a 25% risk. It doesn't save us from overwhelming risks (>90%), though one of those would kill us anyways. But it makes marginal risks extremely marginal, which massively improves our ability to take more productive options without worrying. It massively multiplies our effectiveness, and it gets better the longer we have it, because it returns more value the more of
anything we do.
In this world, the biggest threat is not lacking power, because unless we are constantly taking insane risks the Apocryphal Curse will scale to our power. The biggest threat is an endless procession of very dangerous rolls that we are forced into, and while each individual option that grants power will be subsumed by risk from the Curse, the free reroll scales with whatever situation we're in because of how the reroll mechanic works. And it's applicable to
anything. Combat? Check. Diplomacy/Tyrant procs? Check. Logistical decisions? Check. Cooking tasty food? Check. Loot rolls? Check. Anything.
Hell, if we had a thread participation reroll bonus, it would turn a 50% chance of death into a 13% chance. That's crazy!
This option is worth it alone for 7 Arete, even
completely forgetting the other stuff it's packaged with.
