This is an interesting idea that struck me while working on shadowy antagonists for a game I'm currently running.
Umbral Court Agent enhances the use of the Touch of Darkness ability of the Darkness Domain, among a variety of other things. Eventually this includes grappling targets.
My question is this: If I successfully grapple multiple people via Touch of Darkness (whether that be due to overlapping durations or via the Combat Stamina portion of Domain Strike) is the character restricted to maintaining only one of those grapples using their own actions? Or does the ability continue to grapple automatically over its duration like Black Tentacles?
I think it might be the former by RAW, but the latter feels more like something worth going the 14 levels needed to unlock.
