Finally worked out all the details for this rather casual Halloween event I've had in my head.
Rumors about a storage room by the cafeteria had been spreading throughout the school. As the rumors go, they say that a mysterious force is there and whenever a student approaches it and says "Trick or Treat", they would either receive free candy or be engulfed in a bright light before finding that they've been cursed. While the curses are rather harmless, they serve as an annoyance more than anything, lasting for the duration of a week without faltering once. Curses also apply to Esper when applicable.
It's a really casual, luck event. We could probably make a topic somewhere and just have people post OOC or IC with their character heading to the storage room and yeah. The chances would be decided by a dice roll. 1 - 3 means treat, 4 - 6 means trick. As I said above, the "tricks" are actually completely harmless and won't hurt anyone. All of them last a week from the moment the character receives their results.
Example tricks:
~ Every time a student says (insert cursed person's name), they will pet their head while saying "Good boy/girl!"
~ Whenever (cursed person's name) says I, it will be replaced by their name instead, causing them to speak in third person.
~ Every time (cursed person) hears the word "and", they will spin around and quack three times like a duck.
~ (cursed)'s hair has grown to the length of their ankles. Unfortunately, it cannot be cut and it will grow longer with each attempt.
~ Whenever (person) hears someone laughing, they will call out, "It's not funny!"
~ etc.
You know, really mean pranks basically. I thought it'd be some really amusing thing to screw our characters with. Staff can decide the curse placed on them or the users can choose themselves. No two curses are the same. Go ahead and try your luck twice if you get a candy the first time.
