With all being said, the Orb Devo build is very much advanced. Before getting to that point, you have to make the previous builds. You don’t reach the top overnight. It takes some patience and a lot of grind. So, before getting to the Orb Devo Build, you have to first get the Turtle Build, then the Orb Build.

The First Build - The Turtle Build

When you are at the start of the game, you are an easy target. So, you have to focus on defense. This is where the Turtle build will help you. Your main focus is going to be on the Thorns and the defense stats. Thorns basically allows you to deal damage when they hit you. Each attack you endure will deal back 4% damage. The damage you deal is stackable.
