Hunter's Talisman question.

Would anyone be able to confirm or verify if Hunter's Talisman applies it's effect (stealing 25 life over 5 seconds upon dealing damage to monsters) in a single instance that resets upon additional damage, or if it applies multiple instances upon multiple or consecutive hits within a second?

That may be worded a bit confusingly. If you attack a monster exactly once per second, does this effect continuously steal 5 life per second, or will it deal 5, 10, 15, 20, 25, ... life?

I hope this makes sense.
