I would like to be able to play out a legitimate, unadventurous career as a worminger. I have several unorthodox concepts tied to such an idea.
Please change the system to allow player characters to turn in worm flesh for 1GP even once they reach level 6, but award no experience from that point onward.
You could collect them and then sell them to lowbies at half price. Or less probably. Maybe 3-5 for 1 gold. Not sure how the DMs would feel about people essentially 'buying' xps though.
Find different ways to cook them and sell them at a stall? I'm fine with Stranger's suggestion, 'cause sometimes one needs the gold for sendings as well.
If this is desired merely contact a DM and we will reduce your exp and keep you perpetually level 5.
