This expansion was actually produced BEFORE the game of Magiczny Miecz was made as it was originally an expansion made for the Polish version of Talisman, Magia I Miecz.

Jaskinia or the Cave, adds a new board to the game along with a new deck of cards to encounter.

It is thought to be a very difficult expansion as many of the enemies within the Cave have very high scores for Might or Magic.

It is playable without Magiczny Miecz, with special rules. The goal is to get the Magic Crystal.
