This trap creates an identical double of you. I hope you enjoy being a Twin! Any damage or curses that are applied to one of you is applied to both of you! If one of you faint, you both faint. Cleansing curses do not cleanse the curses for both of you, and require to be cleansed separately. If one has a higher tier curse applied to them, then both will have the affects of the higher tier applied. Stepping on this trap again will not create a 3rd you, and will instead teleport the double to your location. This trap really just spreads resources thin and gives extra chances to be cursed

And of course, since I was already asked these:
The Treat and Box Trap will summon a 2nd box above the other.
The Trap-Trap will condense both into the Same Trap and also creates a double of the Pokemon that was in the Trap. Being freed will release both onto the same tile.
