In Borderlands 3 there are some decorations and achievements you may unlock. To finish the game with 100 percent you have to master all the trophies or accomplishments . To make it easier for you, we would like to describe the next decoration for you in this guide:
Kill enemies with a single sticky grenade
First you need a mod for the sticky grenade. You can wait until you find this mod automatically or you can just buy it at an ammo dump vending machine (green vending machines).
The easiest way to kill two enemies is to go to Pandora, the Droughts. Then find some Level 1 enemies and throw the grenade at them. Both enemies must be killed at the same time.
