This single card was part of the Spiel'19 preorder bundle.

ENTRANCE AND RECURRING EFFECTS
The active player must randomly draw a Monster card from the discard pile and put it in play according to the normal rules.

EXIT EFFECT
The heroes have just claimed possession of Wu-Feng’s Urn. The card isn’t discarded, but is kept next to the Bastion and may be used by any player. Wu-Feng’s Urn is a highly precious artifact which may only be used once - it allows a wounded hero to regain their power and grants them a Call to Arms token. Once the Urn has been used, the player puts Wu-Feng’s card in the discard pile.
