Luminous Wake — ruling 1

When the enchanted creature blocks, Luminous Wake’s ability triggers just once, even if that creature somehow blocked multiple attacking creatures.

Luminous Wake — ruling 2

The controller of Luminous Wake (who is not necessarily the controller of the enchanted creature) controls the triggered ability and gains life when it resolves. In other words, if you enchant your opponent’s creature with Luminous Wake, you — not your opponent — gain life whenever that creature attacks or blocks.
