Cards:
There are four kinds of cards, Characters, Actions, Entities, and Artifacts.

Character cards are your avatar. They are represented in the board with a Character Piece. They have a HP value, move range, and effect text.
HP is the amount of damage they can take before they are killed and you lose the game.
Move Range is the amount of tiles that the character can move when you choose to move as your action.
Effect text is the character's special ability.

Action cards are cards that you play each turn in your Action Phase. They are immediately discarded to the Discard Pile after they are used. They have a cost, a type, and an effect text.
Cost is the charge cost of playing that card. Most actions are free to cast, but some may have a charge cost.
Type is the kind of action it is. It does nothing on it's own, but is sometimes referenced by other cards.
Effect Text is what the action does.

Entities are creatures that you summon to fight with you. They are represented in the board by their own Pieces. They are similar to Characters, but they are controlled independently. They have a cost, HP value, attack damage, attack range value, move value, and effect text.
Cost is the charge cost of playing the card.
HP determines how much damage they can take before they are killed.
Attack value is how much damage they can deal when they basic attack as their action.
Attack range is how close the target must be from the entity for the entity to attack it.
Move value is how far can the entity move if it moves as their action.
Effect text is the entity's special ability.

Artifacts are objects that aids you in battle. They have a cost and an effect text. They are not represented by a Piece, but by a card that you put on the Off-board.
Cost is the Charge cost required to play the card.
Effect text is the artifact's abilities.

Zones:
