Simple, Remix the project with the character you want in this collab. Rules: 1. only one character per person. 2. If you plan to use a character you don't plan on keeping in the collab for long, don't take places like ULB or Dust 3. Keep in mind when you sign up with a character, you are taking the role of a sans in the Ending time octet. (Example: Dust in phase 4 fusing into Satsujinki) 4. I plan on the phase 3s being very lenient, just one thing to note, if you do add characters in your character's phase 3, make sure they either leave or die before phase 3.5 so that way the octet can still continue as normal. 5. Another thing to note, you don't have to use clone animation if you don't want to. 6. keep the Characters as their base character.
HM for Hardmode... I don't think I need to elaborate on this guy
