Block

Keyword
Block is a keyword on some cards whose description reads: For each charge on this effect reduce physical damage suffered till it reaches 0 or your next turn. Cards with this keyword add to the charges and are cumulative. This means that playing multiple Block cards will continue adding to the Block charges thus increasing the number of prevented damage.

Background
Block is a type of card that adds defenses to your character until the beginning of your next turn. In the simpler form of Block cards, such as Simple Block, the amount is fixed. In more complex cards, the amount of defense can vary depending on circumstances.
