Instead, give camp a Netherese portal but make it one that requires an expendable resource to activate it. The camp portal only opens when the sigil is traced with the dust of bloodstone and ash or somesuch. Would have the same effect as the PoE camping supplies but keep the camp dynamics Larian has setup.
(and while we are at it explain why the party is the only ones capable of using the portals)
This is brilliant!
You really should write it to feedback on BG3 launcher so it dont get lost in this topic. :-/
