The Warpwright card attempts to place a teleport trap near the player. It is completely ineffective in the Abyss. It is often better than a Scroll of teleportation in an emergency because the player can step on the trap for an instant getaway, rather than waiting for the scroll to trigger.
The Warpwright card could be found in the following decks over the past several versions.
The warpwright card was removed in the simplification of decks in 0.19.
