I'm always seeing people around me with accesories and I'm like the one person that doesn't have them. I don't know how to forge or find them and I feel like I'm doing something wrong in the game. Can someone please help?
Seems you're a newbie. You don't forge accesories. You can fortify them which is another thing.
To get accesories, you have to do alliance campaign, with another person/s. You complete the campaign and you get accessories based on the difficulty you choose, normal or hard, and the level you choose, 40, 60, etc.
