Eden Eternal how to drop items?

You could sell to any merchant, though some items are not sell-able. Press 'm' to pull up the map, and under the NPC drop-down list you can find a few merchants (armor, weapon, traveling, general, etc.) and you can auto-route there and sell your items. I'm also new to the game (just started playing a week ago) so I'm not sure if there's a way to discard items yet.. >.< I think there are ways to make more space for your backpack (in the beginning you receive one item that gives you 4 extra slots, you have to drag it and place it next to the backpack icon on the bottom of the backpack window, into one of those empty slots, and your backpack space will grow by 4).
