If Hammer of Nazahn enters the battlefield at the same time as other Equipment you control, its ability will trigger for each of those Equipment.

Because damage remains marked on a creature until the damage is removed as the turn ends, nonlethal damage dealt to the equipped creature may become lethal if you attach Hammer of Nazahn to a different creature during that turn.
