Hello Liberator! Thank you for posting.
Normally, when you examine the Dark Alcove marked with a trident in the High Sewers, the game will let you know whether you have the Sharkman's scroll or not. If you don't, the game will say: << Unfortunately, the party cannot resolve this optional riddle because it requires a message from the Sharkman Druid, which can be found in the Water Shrine, during the First Chapter. >>
So, if it doesn't tell you that, you have the scroll and you can recover the treasure using the Spade (not the Shovel - I don't think there's an item called Shovel in the game). Right after closing the dialogue window, press I to open your inventory, then look for the Spade, switch to the character who has it, then mouse over the Spade, then press U for use. You should find the treasure.
If not, please send your compressed saved game to
enquiries@heroicfantasygames.com.
So maybe I can conclude that there's a bug here, just like the riddle master straight jump to the riddle without introduction I encounter a while later?
Not sure, for that too I would need to see the saved game.
Thank you! Best regards
