I want to sell some black pearls to blacksmiths but they only have 2000 or less coins. How often do their stocks reset?
From multiple sources, it looks like the merchants' restock rate for gold is 5 days.
User 1: Never checked when, but heard every 5 days.
User 2: Yea every 5 days....
thay restock every 5 in game days
User 1: So vendors restock money after 7 days? I didn't know that. Back to cow farming
User 2: 5 days actually, dont waste that extra time
If I recall correctly, you need to meditate for 5 days for a merchant to recover some of their gold.
NOTE: It looks like they will only restock some of their gold, however, not all of it.
Their stock reset every 3 days. Unsure about their coins.
The vendors' coins restock every 5-7 days. However, they only restock a partial amount of their starting coin.
