Lord Stonecrest Quest

Lord Stonecrest allows you to obtain all parts of the Ocean Plate Armor, the Heart of the Ocean, and its famous Hero's Amulet.
The Lord's summons may give you a Cape of Elémendil, and Lord Stonecrest only summons when struck in melee, with only summons being able to drop the Cape of Elémendil.
Simply follow the numbers (1 to 13) of the green arrows in order to reach the well that will lead you to Lord Stonecrest's tomb.
The yellow arrows are only used to reach the different chests scattered throughout the crypt, where you can find loot that, in my opinion, is of no importance.
Once you reach the well (located on the gray level at point 13 of the green arrows), click on it.
You will receive 1 Dew-Covered Key.
At the same time, you are teleported to the Lord Stonecrest's tomb level, into a room with 5 chests.
The key to access Lord Stonecrest is randomly hidden in one of the 5 chests.
Your Dew-Covered Key can only open 1 of these 5 chests and will turn to dust after use.
Note that the key to enter Lord Stonecrest's tomb will remain in the same chest until a player finds it.
So in the worst case, a single player will have to walk the path 5 times before getting it if they are really unlucky with the chests.
Once the key is found, it will again be randomly placed in one of the 5 chests.
The respawn time of Lord Stonecrest is 30 minutes.
