Monsters are unique figures that can dramatically change the course of the game. Each has a powerful and unique special ability.
When you play a Monster upgrade, take the corresponding Monster figure, attach your clan’s base to it and place it in your reserve. It is now yours for the rest of the game, counting as one of your figures. You may immediately Invade with it without spending any extra Rage.
Your Monster can die and be sent to Valhalla like any other figure, returning to your reserve in the next Release Valhalla phase. It can gain Glory for you during the Ragnarök phase just like any other figure.
You can only have 2 Monsters as part of your clan at a time. If you discard a Monster’s card in order to place a new Monster in its Upgrade slot, the old Monster figure is immediately returned to the game box.
