Siren shrines new player

Hi have completed 3/6 shrines so far and I'm thinking that those people who do all 6 shrines might get access to new types later on where you can read the symbols as language (because the 6 shrines teach you what the symbols mean) and then be able to read a wall to get to some special loot, really need a Trident you can earn from this these activities that you can equip that can give you some breath melee and shoot. Sharks lol, shrines are great! I feel like I'm in Aqua man world. Just need something special like the trident I mentioned for doing this, I mean Diving down there is a reward in itself for me, and the loot. But Aqua man fan so got to have upgradeable Trident plz 🙂
