Aura of Justice Question

[Pipquin Goldtufts]

Do I have to be within ten feet of the paladin at all times to receive the benefit of aura of justice? Here’s an example, I am within ten feet of the paladin character and he chooses aura of justice, I declare the smite on an evil creature and I move thirty feet away from the paladin and shoot the evil creature with my longbow, do I still gain the smite power? Or do I always need to be within ten feet of the paladin to receive the smite benefit?

I'd think that you don't need to stay within 10 feet of the paladin, but I don't have specific rules to back that up.

You must be within ten feet to be granted the ability to smite. There is no verbiage stating you must stay within ten feet to maintain the ability.
