There are several secret items that can be obtained while playing Terraria, but do you have any idea what they are? Hopefully I can teach you something you didn't know before. However, if you already knew about these items, I give you permission to heckle me.
1. THE DISCOUNT CARD
This is a very explicit item since it allows you to get a discount when you buy items. Other than that, it doesn't have much use. However, we can see that its sole purpose is enough to want to get it.
2. THE COIN GUN
In Terraria, the coin-operated pistol is dropped at an extremely low rate but if you can get it, you won't regret it. This gun, as the name suggests, uses coins as ammunition to damage the opponent. Another cool aspect is that the damage it does depends on the coins you use.
3. THE KEY BIOME MOLD
These are extremely rare and exclusive to the mobile and console versions of this game. Biome key molds are crafting materials from the hard mode, and they are used to make biome keys. These in turn open the biome chests.
4. THE NYMPH BANNER
The Nymph Banner is perhaps the rarest item in Terraria, and is only dropped after killing a Nymph 50 times. What happens when you get it is that a banner appears in the background, and each one gives you a small defense bonus against the designated creature.
5. THE LIZARD EGG
Another rare item in Terraria is the lizard egg and it is also one of the best in the game. In Terraria, a lizard egg allows you to summon a lizard pet to accompany you on your adventure. However, it does not inflict damage to other entities.
