This merchant does not have any Awakening Resource items.

Additional Notes:
You must have not previously entered the location for these Creature Merchants to appear. If you are worried you will have any issues, be sure to save your game before entering the new area/before encountering the Creature Merchant. Then if the Creature Merchant is missing or missing some of it's inventory, shut off the game completely (without saving; don't save if there is an issue with the merchant—it will just save the issue) and open again. Issues only came up when altering the override folder while game was running but restarting the game completely and entering the area for the first time should fix.

Each Creature Merchant can be killed/sent away, weird known quirks Desire Demon will die almost too fast (like before you get a hit in) and Mouse will show 0 when hit but then eventually dies. Some runes are indented to be powerful enough to transfer to Awakenings.
