Nice, I really liked that! I honestly think the ocean monuments are something that maybe was cool back in the time it got introduced, but now it lacks some novelty. There is no reason to visit it anymore. What do you think about a treasure room that has a cool enchantment, like faster swimming? And the Elder Guardian should have a nice item that rewards me for killing it. That would make me want to visit the temples in my playthroughs. What do you think?
