Co-op

Co-op (short for cooperation) is a special feature in Hypixel SkyBlock which allows up to 5 players to complete/progress through the whole game on a co-op profile island.

However, through upgrades from Elizabeth, this number can be increased (see Account & Profile Upgrades for more details.)

Chat
You can send a message to all your co-op members in a private chat channel using. Unlike party chat/all chat in Hypixel, this chat isn't toggleable so you will have to type it every time you want to talk in the Coop Chat.

Managing
If you already have an existing co-op profile, use the  command,   command or Profile Management in your SkyBlock Menu to manage your co-op profile.

Invites
In order to invite someone to your co-op profile, open your SkyBlock Menu and select Profile Management (nametag item), then right-click on one of your empty profile spot. Alternatively, type in command  followed by the username of player(s) you want to invite separated by a space. Note that all the players invited have to be online in SkyBlock. This will create a new profile with a starter Private Island where you and your co-op members can build on.

To start a new co-op profile, you need to use the command  and wait for the player(s) to accept.

To add a new member to an existing co-op profile, use the  command.

To view your current invites, use the  command.

Kicking
You can remove a co-op member if they have not logged for 35 days. To kick someone from your co-op profile, use the command

Leaving
Make sure you're on a different profile before you leave a co-op profile. When leaving a co-op profile, if there's still at least a member on it, the Private Island will still remain available for them. All your items and progress on the co-op profile will be removed and is salvageable by your co-op members.

Salvage
If a co-op member has left/kicked the co-op profile, you can collect their items within 36 hours by using. However, when salvaging when the person has deleted their profile, it takes time for the game to register this. It should take around 5-15 minutes and the command should work.

Salvaging will salvage players' inventories (including armour), ender chests, purses, personal banks and bags.

It is not entirely clear whether pets, accessories, sacks, quivers and personal vaults are also salvageable.

WARNING
Only Coop with people you trust, as they could potentially scam you out of your island.
