NRR: Nidavellier - Idavoll

About Nidavellir: Idavoll, from BoardGameGeek:

Idavoll is the second expansion for Nidavellir. During the first three rounds of the Age 1, the second tavern offers Mythical Animals, Aesir, Valkyries, and Giants, which add an additional round to the game. Each new type of card also adds never-before-seen effects. Gods: When you recruit a God, put the card in your Command Zone with 1 Power token on it. Discard this token to use the God's power. Giants: When you recruit a Giant, put the card in your Command Zone and place 1 Capture token at the bottom of the column of the matching class. Each Giant lets you capture a Dwarf of the matching class. Valkyries: When you recruit a Valkyrie, put the card in your Command Zone with 1 Strength token on the highest notch. Whenever you meet one of the Valkyrie's requirements, move the token down a notch. At the end of the game, earn victory points depending on the position of the token. Mythical Animals: When you recruit a Mythical Animal, place it in your army in the matching class. Each animal has its own unique ability.
