Vampire: The Eternal Struggle

For a directed action, only the Methuselahs targeted—or who control the targets—may block. An undirected action can be blocked by your prey or predator, with your prey getting the first opportunity; political actions are always undirected (pp. 20–22).

You can add stealth only when a block is being attempted and the blocker has enough intercept to block you; a blocker can add intercept only when your stealth exceeds their intercept. A block succeeds when the blocker’s intercept is equal to or greater than the acting minion’s stealth (p. 21).

A ready, untapped minion can take an action, and taking one taps it. But even if it untaps, a minion cannot bleed more than once or take more than one political action in a turn (pp. 16–17, 19).

No: an action’s cost is paid only if it succeeds, and a blocked action has no effect. Any card played from your hand to take that action is burned if it is blocked (p. 22).

During your influence phase, spend transfers to move pool counters onto the vampire; at phase end, it becomes controlled when it has blood equal to or greater than its capacity. Normally you get four transfers, though the first three players get fewer on their first influence phase (p. 32).

When your prey is ousted, you gain a victory point and six pool, and your prey changes to the next player in the seating order. The game ends when only one Methuselah remains; the winner is whoever has the most victory points, and the last player left gets an additional point (p. 33).
