Devoid is a characteristic-defining ability. “Devoid” means “This object is colorless.” This ability functions everywhere, even outside the game. See rule 604.3.

Ingest is a triggered ability. “Ingest” means “Whenever this creature deals combat damage to a player, that player exiles the top card of their library.”

If a creature has multiple instances of ingest, each triggers separately.
