Eternia is a strategic card game in which 2 summoners duel to overcome their opponents. The players have a long list of monsters and spells at their disposal, and use these to vanquish their foes.
Goal
Bring your opponent’s life from 300 to 0 by casting your spells and attacking with your monsters.
Setup
Each player starts the game with 300 life and a deck of 36 shuffled cards: a mix of monsters, mana, and spell cards. Each player draws 6 cards from their deck, then chooses to discard any of them and draw that many cards minus one. Then anyone may put any mana cards from their hand onto the arena. Then choose which player will go first.
The Turn
Phase 1: Mana Phase
The current player may put any mana cards from their hands onto the arena. Mana allows you to summon monsters and cast spells, which all cost mana to put onto the arena. Expended mana cards can not be expended again.
Phase 2: Summon Phase
The current player may put any monsters from their hand onto the arena, as long as they have expended enough mana to cast it. When you use the mana for monsters or spells, expend the number of mana stated on the card.
Phase 3: Combat Phase
The combat phase has 3 parts: the assign attackers phase, the intercept and ability phase, and the damage phase.
Combat Phase 1: Assign Attackers Phase
The current player chooses and expends any monsters they control and targets one monster or player for each of them. Already expended cards can not be expended in this way.
Combat Phase 2: Intercept and Ability Phase
Either player may choose to play a spell card, activate an ability, or the current player can intercept. Cards with the keyword intercept may choose to take the damage of something that is being done to another player or monster. All combat damage is resolved as if the monster this card has intercepted fights the monster with intercept.
Combat Phase 3: Damage Phase
During the damage phase, all enemies that were expended to attack and the monsters that they chose to attack are each in a separate encounter. In an encounter, one monster deals damage to the other monster equal to the damage-dealing monster’s attack minus the attacked monster’s defense. Each monster deals damage this way. If a monster was chosen to attack a player, that player loses life equal to the attack of the attacking monster. The player does not deal any damage to the monster. If a monster dies at any time (with a life total below or equal to 0), it goes to the controlling player’s discard pile.
Phase 4: Refresh Phase
The current player draws a card. The turn switches to the current player’s opponent.
Losing the Game
A player loses the game if their life total equals 0 or that player has to draw a card from an empty deck.
Spells
Spells can be cast at any time, unless the card states otherwise.
