Hopo Better Underwater Ruins

--- Call me a City! --- ♦ Renamed structure to "underwater_ruins" to "underwater_city", makes a lot more sense and fits better, you can see this change when you /locate structure ♦ Changes on loot tables, after a lot of play testing that i did, i make the loot more worth it, now you will find more stuff ♦ Changes on structure distribution, now they will generate more like a "city" and also improve the some pieces of the structure ♦ Fixed a bug when small ruins or fossils, generate with floating water outside the ocean, making them look weird ♦ Underwater city no longer generates on frozen ocean, Drowneds said that doesn't look like the perfect place of build a underwater base ♦ Some pieces now will generate with some Decorated pots ♦ Added new drowned mob type! This one is basically a ninja, moves fast, has an iron sword, good luck with this one! ♦ Drowneds now will have fancy armor trims in their armors ♦ Make structure a little rare to find, since they are now too big ♦ Added new advancement, "Not Quite Atlantis..." when you find an underwater city. Good luck there :p ♦ Small ruins will now spawn a little frequently around rivers, this change was made to incentive players to play with archaeology ♦ Added some details (block pallete) in the city and ruins ♦ Guardians spawn next to cities ♦ Fixed some air blocks generating in the middle of the ocean ♦ Improve path structures, underwater fossils structures ♦ Archeology loot includes stuff like: (enchanted books, sherds, weapons, armor trim, armor, a special banner, banner pattern and more!) ♦ And probably more stuff that i don't remember lol, this update is sick, and makes ocean more alife, enjoy!

• Also "b" version at the end is because i'm reupdating the file, to give forge compat
