The latest Slap Battles update has added Bind Glove and to get it, you will have to get the Lost One badge. However, it seems to be an error from the devs side as the new badge added to the list is actually the Garden of Erasure badge.
It means that in order to get the Bind Glove, you will have to get this badge and here is how to do it.
How To Get Garden of Erasure Badge In Slap Battles
The description of the badge says, "The Garden is forever shifting, no one person will face the same challenge. Will you be able to awaken what lies deep within this forgotten labyrinth?"
You will have make and drink an Alchemist potion, that is made using 3 Elder Wood, 1 Blue Crystal, and 1 Red Crystal, to teleport to a maze.
You will then have to find a room within the maze while getting chased by a damage dealing entity. The room will have Bind glove in it and all you have to do is click it to get the Garden of Erasure badge.
However, keep in mind that the badge description mentions, "no person will face the same challenge." It means that the maze for each player will be different and even you will get a new maze if you get respawned, so you need to find your own way out of it.
We would like to thank premiumsalad for helping in clarifying doubts for getting the glove, so make sure to check out their video and subscribe their YouTube channel.
