To Anon above this post: View the last number of your Lunacy reserves. Then, clear 7.5-11 using only the second most recent Identity released for the Sinner that correlates to that number.
To Anon below this post: Select a team of five Sinners whose numbers sum to 25. Clear stage 4-22 using only their base Identities, ensuring no Sinner falls below 50% HP.
To the next Anon with a post number ending in 4: Check the current Enkephalin Module count. If it ends in an odd number, complete a Normal Mode Mirror Dungeon with only Sinners #1, #3, and #5, using their most recent Identities. If even, use only Sinners #2, #4, and #6.
