There are a total of 48 trophies to unlock in Sword of the Sea, covering a bunch of activities and challenges. Here is our guide to help you unlock the Wisdom of the Ancients, Boiling Cavern Shell Collector, and Frog Skeleton in Sword of the Sea.
Check out our Sword of the Sea Review to get our full thoughts on the game.
The final chapter in Sword of the Sea is a short but hot one! Similar to Forbidden Valley and Frozen Drifts, there is a short list of collectibles. There are only five shells to collect, for the Boiling Cavern Shell Collector, and three stele messages, the last ones needed to finally pop the Wisdom of the Ancients trophy. Almost all of these collectibles will be easily missed, so make sure you look at the time stamps on here or on the description of the video so you don't miss any of it!
COLLECTIBLE NAME | TIME STAMP | NOTES |
1/5 Shell | 00:00 | In the next area, jump towards the end of the room past two sets of stairs. The Stele you need is behind a closed gate. To open it, go left to grab your water bubble. You'll need to quickly activate a switch in order to lower two platforms, jump over, and drop off your bubble to open the gate. The Stele message is just behind a rock. |
1/3 Stele "The Fires Below" | 00:22 | Jump over the rocks that are behind the stele message to get on top of a narrow ledge on the perimeter of your vicinity. Hug that wall, jumping to the two available platforms until you're just above some stained windows. |
2/5 Shell | 01:28 | After a brief cutscene, head towards the building sinking into the lava on the right side. Jump onto two boats to reach a tucked-away corner of the room and read your next message |
2/3 Stele "The Army of Red Fire" | 01:49 | Earlier, when trying to reach the previous message, we passed by a boat leaning diagonally against a wall. Go back there and use it to get on top of a narrow ledge on that wall. Once up there, head right and follow it until you reach an opening on the right side. |
3/5 Shell | 02:45 | Head back to the entrance of this area, and this time, go towards the immediate left side. Go behind the broken down wall, there is a small platform. Use that to get some rest from the lava and brace yourself as you jump your way through the end of a narrow path. |
4/5 Shell | 03:24 | Upon entering the next area, you'll see a skeletal creature, and in the middle of the room is your final stele message of the game. Morbidly grind against that skeleton, read that message and your trophy "Wisdom of the Ancients" is finally yours! |
Skeleton Frog | 04:03 | Before leaving this area, turn around. Make your way towards the left side and follow some elevated platforms to reach a boat that is just about to tip over. |
3/3 Stele "When Water Battles Fire" | 04:34 | Upon entering the next area, you'll see a skeletal creature, and in the middle of the room is your final stele message of the game. Morbidly grind against that skeleton, read that message, and your trophy "Wisdom of the Ancients" is finally yours! |
5/5 Shell | 04:58 | For the final collectible, jump on the platform that is just behind the stele and hug the wall to the left until you reach a small opening. This will net you the "Boiling Cavern Shell Collector" trophy. |
*Note: The final trophy associated with collecting Shells, called "Water Whisperer", won't be attained until you've purchased all the Vendor's items, which requires 5000 for the final item. This will most likely happen in your New Game Plus Playthrough, which is also required if you are hunting for the "New High Score" and "New Game Plus Completed" trophies.
