GW2 Tiptoe achievement can be obtained if you complete World 2 Zone 1 without angering any Hillbilies. Most of them you can easily bypass, but the last group is little tricky. After the part with wooden beams, you will come across a Shop Keeper house (you can see the Zone chest in the cage behind the house, in the distance). When you turn right, you will see two Hillbilies on the main road. Next to the Shop Keeper house you will notice a yellow barrel. Destroy it and a crescent will appear. Just run through it, and you’ll become invisible. Also, avoid red barrels because they explode.
