Improving fishing in the Dungeon - why give the Dungeon unique fishing stuff if you're only going to go halfway on it? I propose a massive increase in Dungeon fishing content. Includes new items, fish, and potions!
Adding more enemies to hybrid biomes - ever notice that the only hybrid biome that's
really different is the Underground Desert? I'd like that to change. Includes new enemies and weapons!
Evil biome Summon weapons - there's currently no minions connected to the world evils. I've come up with some ideas for what they could look like. 2 new post-mech Summon weapons!
More buildings on sky islands - I love sky islands, but why is there only one kind of building on them? Let's see some more variety. Contains concepts for several new types of structures on sky islands (as well as a few example pictures - I'll add more later, I promise!)
Improving the Jungle Temple (and the rest of late Hardmode) - the Jungle Temple is pretty boring. I've come up with a major rework to the experience, while trying to maintain its identity and feel. Contains new enemies and concepts for features in and around the Jungle Temple!
