Portals

Portals are items that players can craft and place on their island. They provide a way to quickly travel to the corresponding destination. While Travel Scrolls perform this task more efficiently, they are notably (20 times more ender pearls and generally about 160 times of the specific materials) more expensive in comparison.

Crafting
To craft a portal, the player must first unlock its recipe as a Collection reward. The recipe will always require 16 Ender Pearls in the middle and 16 of each specified items around it.

The exceptions to the above are Portal to The End and Portal to the Gold Mine. Both requires 16 Enchanted Ender Pearls instead of 16 normal Ender Pearls.

Placement
Portal placement requires an empty area of 9 blocks wide x 5 blocks deep x 15 blocks tall and will spawn with the base centered on the selected block, facing the direction of the player.

Removing
If a portal is misplaced, it can be clicked on to trigger a prompt to delete it. Deleting a portal will not give the player the item back or allow the player to reactivate it, leaving the frame. The same menu allows the player to disable the hologram if they find it annoying.

After placing, any/all blocks of the frame can be removed without destroying it, leaving only the portal itself. The portal will disappear only when it is destroyed by clicking it and then confirming deletion.

The Hub Portal can be removed from the player's island from the Jerry menu. This action requires at least Level V in every skill.

Portals used to be removable (block by block) using Water Buckets, but this feature was later replaced with the above system. Some profiles still to this day have semi-broken portals because of this.

The Jungle Island Portal and Dark Thicket Portal both have incorrect descriptions, each displaying the other item's description instead of its own.

Trivia

 * The player PortalHub has a collection of all the portals to various locations. The command  /visit portalhub  or  /visit prtl  or /visit BenC1ark can be used by players who don't have the rank requirements for faster methods of traveling.
 * Due to the release of Travel Scrolls it is unclear whether more portals will be added, even if new islands are.
