I've never been fond of random encounters. It's a really annoying dynamic to run into when you've just made it through a tough fight. "Great! I finally killed the bullette, out of spells and healing, guess it's time to crawl back to camp. Ah! I just got killed by some gnoll randos while traveling, time to reload . . ."
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)
