Act 1 is a Collectible in Phantom & Crimson Solitaire, added in its Expansion II.

| —Message after the player obtains Act 1 |
Should the player have Act 1, clearing 5F will cause the player to enter 6F instead of completing the run with New Chapter as the Dreadful Foe, which will complete the run with the Silent Chapter ending when cleared.
Acquisition
Act 1 is obtained by clearing Observation, which is accessible by choosing "See what they're writing" in Encounter: Revenge Story that will only appear when the player has 
Dance of the Condemned.
Since Bound by Self where the Dance of the Condemned is obtained is only accessible through Encounter: Don't disturb them which is added in Crimson Solitaire's Expansion II and will only appear in the following runs after the player had completed a run from that point, it is impossible to obtain Act 1 before then.
