Situation:
In a battle sequence our Paladin (Oath of Vengeance) has successfully cast Hunter's mark, later in the battle our Wizard cast Silence.
We know that Hunter's Mark requires V (verbal) component to cast, but is it also required to "Move" the spell? Can the paladin move the "Hunter's mark" to a new target when he has been silenced?
Moving Hunter's Mark is not casting the spell again and simply requires a bonus action:
If the target drops to 0 hit points before this spell ends, you can use a bonus action on a subsequent turn of yours to mark a new creature.
The spell only needs to be cast once (note that the spell never ends during this process), then as long as concentration is maintained, only a bonus action is needed to mark a new creature. This means that the act of moving is not casting and does not require anything else, including components, so it is not affected by silence.
