Hunter's Call and Sunken Kingdom feels woefully neglected and I brainstormed some ideas to breath life into both simultaneously. So you get a voyage from the Hunter's Call and you have to go to one of the Shrines to collect a summoning idol, similar to the Breath of the Sea. Most of these idols will be a Crab Idol that you take to one of the Sunken Treasuries and use it. You fight waves of enemies as usual, but at the end you fight a giant Crab monster spawns and you have to fight it. On special occasions you get a summoning idol to summoning a Megaladon, or Kraken. Each of these Sea Monsters drop special loot that can be sold to the Hunter's Call. Meg Teeth, Kraken Ink, Crab Carapace.
We can also start an emissary for the Hunter's Call that can be earned by doing the usual fishing, or collecting loot from these Hunter Call voyages.
