In multiplayer games (3 or 4 players), how do you pick battlefields and what are the card draw rules?

Ruling: In a 3-player game, each player provides one randomly chosen battlefield. In a 4-player game, everyone except the player going first provides one randomly chosen battlefield. The player going first doesn't draw a card on their first turn, and the player going last channels an extra rune on their first turn.

Sequence:

• Battlefields are randomly chosen from players (all players in 3-player, all except first player in 4-player)
• First player does not draw on their first turn
• Last player channels an extra rune on their first turn
