Poseidon's Ritual

Poseidon's Ritual would be a raid event you could trigger at an Ocean Monument, or some other future structure. This would spawn waves of drowned and other nasty ocean creatures to fight off. You would want wanted enchanted gear, water breathing potions or a conduit. A beacon of your loaded. During this raid, Guardians may or may not attack the player, being focused on the other threats. Loot would be ocean related, but completing the event would grant Poseidon's blessing. A effect that would grant fishing buffs, extended breath and faster swimming. It could even prevent drowned from spawning near the player. Minecraft would benefit from more raids. More activities to do keeps players playing longer.
