Introduction
This guide is designed to help the farmers of Coral Island collect all of the artifacts currently found in-game to get the "Momento of the Past" and "Part-Time Curator" achievements. I have organized them in the order that they appear in the journal to aid those who may only be missing a few from their collection. I have included photos of the artifacts, the coffers they can be found in, drop percentages, enchanting value, and selling prices.
All artifacts in Coral Island are found inside of Coffers by breaking them at the Blacksmith. Coffers are found at different depths when clearing trash in the ocean. The easiest way I found to farm for these coffers is by clearing trash within the ocean caves that are unlocked after discovering the Merfolk Kingdom and getting permission to visit the caves from Oracle Cho Oyu. I also recommend upgrading your scythe and enchanting it with Rare Drop to make these coffers more likely to drop. The types of coffers are as listed below:
Coffer Type Diving Depth Possible Item Drops Coffer Any Depth 21 Artifacts Trash Glass Scrap Bronze Kelp Silver Kelp Mysterious Coffer Any Depth 57 Artifacts Trash Glass Scrap Bronze Kelp Silver Kelp Ornate Coffer 10-20m 13 Artifacts Trash Glass Scrap Bronze Kelp Silver Kelp Shimmering Coffer 20m+ 13 Artifacts Trash Glass Scrap Bronze Kelp Silver Kelp Marble Coffer 40-50m 14 Artifacts Trash Glass Scrap Silver Kelp Gold Kelp Pirate Coffer 50m+ 12 Artifacts Trash Glass Scrap Silver Kelp Gold Kelp
My biggest tip if you are searching for only a few artifacts is to collect a ton of the coffers that drop the artifact(s), and break them all open at the blacksmith at the same time. If you do not get an artifact you need, simply reload the game and open them again. Repeat until you get something you DO need.
Please note that the Black Market may also randomly sell the artifacts or coffers you need.
Please let me know if there is anything I missed, and I hope this helps! ♡
