Hoping to get an FL opinion about this but also interested in seeing if the community reaches a consensus. There was some talk about it on the Discord but no consensus emerged.
Suppose your group includes more than one Barding with more than one person who took the Cram ability. At a short rest, is the endurance recovery increased by all of them at once (i.e,. does Cram stack), or only the best score amongst them? The former seems to match rules as written, as nothing precludes it, but perhaps that wasn't the intent, or this scenario wasn't considered.
