Trickster item idea

New item: Trappers serrated dagger.
Perk: When you activate switch strike, place a trap at your targets feet moved switched. You gain life proportionate to the amount of damage the person takes while in the trap.
This would encourage tricksters to have a more mobile playstyle because they do not have to stand inside a trap in order to use it correctly, and reward fast players with some small healing with it.
