When Revealed: Shuffle the encounter discard pile into the encounter deck and discard cards from the top until X enemies are discarded, where X is number of players in the game. Add those enemies to the staging area.

A new force of Goblins has scaled the cliff above the gate and attacks you from the rear.
Forced: After an enemy attacks, place 1 progress on The Goblins' Assault.

Forced: At the end of the round, if there is X or more progress on The Goblins' Assault, advance. X is equal to 4, plus 4 per player.

Hammered now on two fronts, you struggle to hold the gate.
