Thank you for taking your time to reach out to the support and we're sorry to hear you are having issues with the Ring item.
The Ring item is located on a small island with gold barrels to the East (Right side) of the starting zone (The area with the tool upgrade), initially to get there you go through the underwater cave found to the north-west (After the toxic graveyard area in the upper left from the starting zone).
If you can't find the ring there please contact our support and they will be more than happy to assist you.
Happy adventuring!
