How do u feel about something like random NM gathering spots? Like an old tree thats alive that failing to to gather from it injures or kills the player? Or giant fish NM that put up quite a struggle and could kill you by dragging you into the water. Or perhaps your a miner and the mining spot could be unstable but be teaming with rare ores, however failing to succeed your gather causes and avahlance. For crathers how but NPCs that appear in the field at random and offer rare items for crafting if you can repair their gear. Just feel this would be interesting for the world as is.
