Hey everyone,

I'm playing on a Minecraft Java Edition 1.21.11 server hosted on Aternos and looking for a working early-game item dupe.

Since I'm still early on, I don't have late-game items like Shulker Boxes, End access, or complex Redstone setups yet. I'm looking for simple, low-cost methods (like basic chest/inventory timing, donkey/entity setups, or basic vanilla mechanics) that actually work on a Java Aternos server.

Does anyone know of any working methods for this specific version/setup? Thanks!
