If multiple creatures block a creature with afflict, afflict triggers only once.
If a creature is attacking a planeswalker, that planeswalkerâ€™s controller is the defending player.
Afflict resolves before combat damage is dealt. If this loss of life brings a player to 0 life or less, that player loses the game immediately. A blocking creature with lifelink wonâ€™t deal combat damage in time to save that player.
Afflict causes the defending player to lose life; itâ€™s not damage or combat damage.
