Make ur own barrier to trap some kind of species! Here's a comment from one of our customers! "I'm really glad I can seal those DANG Insane people in the Asylums they belong in-" And here's smth from the monster who it was used on, "ITS TERRIBLE! LIFE UNDERGROUND IS TRASH! Wait, how did u get here anyway, punk?! H-hey where are you?!-" Anyway, enjoy~
"YESSSSS LOL! GET TRAPPED MONSTERS!" Said the terrible humans. hey don't forget, anything can pass through it but nothing can leave once trapped. The seal can be broken if whatever you want it to be used like say a human soul. Seven of them. then there you go. The monsters need seven human souls!
