hallow’s eve m!as — all m!a’s will last for the entirety of october, or however long you want. anon is allowed to change the time duration —

Trick: Deceit lies in every trick– your muse now can’t help but tell unscrupulous lies! Will the truth be uncovered?
Treat: Sugary sweet- the way we all like it. Your muse will always have a treat up their sleeves, compromising to produce one to give to others. Sounds terribly kind, no? Perhaps it’s more of an annoyance than anything…
Pumpkin: Look at you, all orange and spooky for the season– well, not exactly! Your muse suddenly became– you guessed it — a pumpkin, free for anyone to paint… or carve to what they see fit. Don’t worry, it won’t hurt too much.
Spooked: Your muse is such a coward! They’re startled by anything– may it just be a simple drop of a pin. Even a harmless ‘boo’ would get them to scream for mercy.
Light in the Dark: There’s no more sun in your muse’s world– they only see darkness, also can be known as some sort of blindness. However, if they hear any type of noun, they would be able to see the mentioned object in its full glory. It has to be heard from someone else, however.
Lost Facade: To your muse, everyone donned in costumes act exactly like whomever they are dressed as. Only a mere illusion, however, and the only way to fix it is for others to take off their costume.
Salvation: Is it really true salvation? They are saved from the nightmares, the horror that seeped into their lives. However, all of that comes with a price: they’re ignorant and lost all of their memories.
Transform: Anon gets to specify which creature your muse turns into– this is merely an curse, rather than a blessing. The downsides of being that creature increases tenfold, the weaknesses begin to shine more than the strengths.
I’m too lazy to come up more, so feel free to add some!
