Set up a cooperative End Portal with your team
Gather your team and Eyes of Ender
Before approaching the End Portal frame, ensure all players who will contribute have crafted or obtained their Eyes of Ender. Each player can only place a limited number of eyes into a single portal structure, so coordinate who will contribute and how many eyes each person needs.
Place eyes together in the portal room
Have each team member take turns placing their Eyes of Ender into the End Portal frame blocks. As each eye is placed, you'll receive a message confirming you're committed to this portal. Continue until you've placed enough eyes to fill the frame—remember, you're limited in how many you personally can contribute.
Gather all contributors in the activation radius
Once all eyes are placed, every player who contributed an eye must stand inside the portal room within the activation radius. The portal will only activate when all contributors are physically present. You'll see an action bar update confirming the portal's status. Once everyone is in position, the portal will open and you can enter the End together to face the Ender Dragon as a unified group.
