Many rooms in the Sanctum will offer you a choice of currency items.
You can take the reward now or leave it behind, with the promise of an even larger reward later.
Deferring your reward to the end of the current floor or even the end of the entire Sanctum escalates it with great risk. If you run out of resolve before reaching this goal, you lose everything you gambled. Do you believe in yourself enough to take the risk and potentially reap a massive reward? Or do you play it safe and leave with what you have?
