Parallel Universe is the fifth episode for the Thief.

In the Parallel Universe episodes, all of the player's equipment has been changed to new, more complex equipment. Enemy health is also raised by 10%, similar to the Elimination Round (Thief) episode.

Also, status effects are changed. For example, when Burn happens, it instead causes the dice to make the equipment used unavailable for the next turn (and for the rest of the turn if used on a multi-use item).

The Thief's Limit Break is Unlucky Roll, which rolls four 1s. However, in this episode, the Silence? status effect will weaken it to Very Unlucky Roll, which rolls only two 1s. His character skill lets him use one of the enemy's pieces of equipment at random.

You always copy one random item from the enemy each turn during the fight.
