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/curse] a new creature.
Both of these spells have spellcasting components that would be observable to another creature when the spell is initially cast. If I want to mark or curse someone, anyone nearby will know.
If the original target is reduced to 0 HP, is it observable in any way should the caster choose to transfer their mark/curse to another creature? Or is this essentially untraceable after the initial casting?
Obviously for this question, I am ignoring a sorcerer's Subtle Spell metamagic. We can also assume that this is not from stealth; the caster is not trying to hide what they are doing, this is more about whether or not there is anything to hide beyond the initial casting.
- Is a creature aware that a Hex or Hunter's Mark spell has been cast on it? (but related to the initial casting from stealth)
- Are Hunter's Mark and similar spells noticeable to the target? (duplicate of the above, still about the original casting)
- Does moving the curse from the Hex spell to a new target have any spell components? (regarding if the transferring part requires components)
