Each character starts their turn with three cards (drawn at the end of their turn, so susceptible to enemy card shenanigans), each costing an amount of Willpower from the communal pool. Will is usually generated by discarding cards, but the character that discarded them can instead choose to either make a simple two hex move or remain stationary to get some armor. The last bit is, I believe, something that wasn't in the Early Access version, and is a much-welcome addition. Not having to rely on specific cards for defense (which is halved at the start of your turn) can be the difference between life and death.
