If the affected creature gains an ability after Heliod's Punishment becomes attached to it, it will keep that ability.

If the enchanted creature has an ability that defines a * in its power or toughness, that * is 0.

If a creature is enchanted by two or more Heliod's Punishments, it has only the activated ability of the one that most recently became attached. Activating that ability removes a task counter from only that one.
