River stone
Worn smooth by the spring floods, and it still feels faintly of running water in the hand.
A keepsake. Nothing in the game uses it, and it is not trash: selling all your vendor trash leaves it alone. Stacks in one inventory slot. Vendors pay 1 coin for it.
When it turns up
Found during Spring Equinox, 14 to 27 March every year, from any fight won or node worked: about one an hour of either.
What it trades for
