Final Fantasy V Pixel Remaster - Part 21 - The Great Sea Trench

The heroes go deeper into the world to get the third tablet that would unlock more of the legendary weapons that would allow them to defeat Exdeath. (I hated this dungeon so much. I hate it so much that I wish it wasn't necessary. Every single battle was so long, it's as if every single battle was a mini boss fight. I recommend getting through this dungeon as quickly as possible.)
