You could re-roll the first level you do in order to get your preferred "Divine Delegate" event buff, but your fate will always be "Laziness" if you ever reset a Chaos without progressing first. This isn't very great because some fates are very powerful like providing morale buffs or double hits to basic cards.

• Because resting in a Safe zone takes approximately the same amount of time as trying to skipping the warning message, resting is still worth it to preserve your combatants' stress levels.
• Sometimes at the end of a run your characters can still be effected by the chaos and force the game into nightmare mode, you can either go to the Epione center to cure it or just play the rest of the run in nightmare mode.
• It's advised to have your potential levels to at least the first node to gain an initial random epiphany
• You can skip the Epiphany animations by not using highlighted cards in battle. At the end of the battle it will be a latent epiphany.
• You can cut time by skipping claiming rewards
• Although the map layout is random, the events in the game are only semi-random, and all of the events in the game have predictable outcomes, it's advised to pick options that avoid fights, gain credits, or gain equipment to progress quickly.
• A higher exploration level unlocks the potential to see more equipment and cards, but dilutes the fate pool.

The hardest level is generally considered to be "The Blue Pot" the final interior boss is much easier to deal with having neutral cards like "Rally or Wanderer of the Void" or any other skills that increase enemies action count.
