Idea for ocean update

Atlantean like city kinda like the counterpart to woodland mansion, 4 new mobs (3 mermaid like illagers using swords, tridents and crossbows. fourth mob, the “Brine” water variant of breeze and blaze) new weapon, enchantment and armor trim. Idea for weapon “charge staff” needs the elemental rods of all three elemental mobs to craft or other idea; just two brine rods plus exclusive item to that structure for the build (kind of like the heavy core). Weapon can melee (whack) shoots a random charge of any of the three elements. Super rare structure like a woodland mansion. Add Sharks
