There a few items I can think of that are driven by martket like you mentioned.
Mainly ones that are to consider are the ones used for imbue that are not looted by bosses or can be exchanged by Gold tokens
Some of the examples I can give that have usually a good price:
Fiery hearts, polar bear paw, flask of embalming fluid, gloom wolf fur, swampling wood, blazing bones, winter wolf fur, cultish masks, bowl of myrrh, elven hoofs and scouting glasses, elvish talismans, broken shamanic staffs to mention the ones I can think of.
Other items are the rings/amulets from Gold token monsters for all vocations mainly knight ones being the most expensive
The lamp used for the paleworm is also only driven by market
hope my examples are of great help
yours, James Decross
