We have begun migration of most wikis to our new host, Amazon Web Services. All but the top 100 wikis are in read-only mode until the migration is complete. Estimated completion: TBD -- Update: Fri 10/20 11pm UTC - We have encountered some unexpected issues. Our staff is working around the clock to complete this process as quickly as possible. Thank you for your patience.
From Terraria Wiki
The Iron Crate is the middle tier of crate, containing various potions, bars, coins and rare items.
- You can receive up to 5 items from a single crate (Ginger Beard/Tartar Sauce/Falcon Blade, Bar, Buff Potion, Healing/Mana Potion, Coins).
- You always get at least one item, as empty crates are re-rolled. This also raises final average yield somewhat.
