Investiture spent into an object so a surge continues without you there. It expends 1 at the start of each of your turns and ends when it runs dry, so infusing more up front simply buys more rounds. A surge on yourself needs no lump sum — it draws from your current Investiture each round until you end it, no action required — and surges continue even while you are Unconscious. At the start of your turn, before infusions expend, you can add Investiture to one within range, and several can run at once. Outside combat that round is longer: roughly a minute in a conversation, 1 to 10 minutes in an endeavor, and about 10 minutes when no scene is running at all.
