I'm not going to comment on the feasibility/desirability of the OP - y'all are doing a great job discussing that and the various strategies are fascinating.
What I want to inject into the conversation is my desire for a way to learn about mobs w/o killing them. I don't have a problem w killing a deer for meat, or even for a head to make a helmet out of - but killing a whole bunch of ANYTHING strictly for 'information' and leaving the piles of corpses unlooted bc I already have plenty of meat or hide feels horrible & wasteful.
If mob drops get tied to knowledge and only killing gets me knowledge, this may not be my game after all...
But I'm hopeful that this will be addressed by @Prometheus & the mighty devs in future iterations bc thinking up a world like Arboreus seems to intuitively mean they grok folks like me.
Suggestions for (believable) ways to learn about things w/o killing mass quantities:
- using looted materials in crafting
- 'lessons' from an experienced hunter/craftsperson
@Specter and the mods can move this to another thread if it seems like a completely separate conversation.
