I have a suggestion, and it is about the uncreated page: Earth Harpy. Maybe, It would have low movement speed, high defense, and drop 'The Earth Feather', which can craft Earthen Wings, which increase player defense, but weaken movement speed and jump height and has the tooltip: How does it fly?
In this mod, i have an idea. What if the Angler NPC didnt spawn on the beach until Water Spirit has been defeated? And what if the Stylist didnt spawn in the spiders nest until Queen Spider has been defeated?
We have a new boss for almost evry biome (Blizzard Elemental for Snow Biome, Steel and Solar Wyverns for Space Biome, Devil Lord for Underworld, Sand Lord for Desert, Keeper of Nature for Forest and Queen Spider for Caverns) but we dont have a jungle boss.
