Afflict is a keyword ability introduced in Hour of Devastation. Afflict is focused in red, and present in blue and black.
Whenever a creature with this ability becomes blocked, defending player loses life equal to the Afflict value.
Called "unstoppable" in design, the mechanic was created to convey the destructive and vicious power of the God-Pharaoh's legions, the Eternals.
