About alliance battles: When you attack another alliance, are your chances of winning completely randomized? It kind of feels like it, to be honest. Or does it have to do with your alliance's strength? As in, if yours is lower than the other's, they're bound to win, etc.

About relics: What is the use of relics such as Bead necklace, Sword, etc? As in, the relics you can't really do anything with, and they just kinda sit in your hoard. Do they actually have any use whatsoever, or are they just meant to be crafted and then sold for profit?

Most relics are just for selling. Except for potions, pottery and figurines, they don't have much else use.
