I have a list of possible ideas here:
More common daybloom
Prefixes for armour
Dye for weapons
Less common Crimson worlds
A set of travelling merchants wings
A steampunk biome that has a giant robot mob that drops an ingredient for the steampunk wings. When the steampunker lives in that biome she could sell a robot pet summoner
Paladin armour dropped by paladin
a tank mount
