ive been farming the spiders and i seem to get most rings on all banners, but when it comes to neck and banners, for me orc have the lowest chance of spawning, like i main galek and i just reach 50, doing the stage of spider that rewards all 3 accessory with 3-5 star, and all i got for my orc is ring while my other characters can equip if i just ascend them.....maybe they should add a method where instead selling the accessory we reroll them, like 5 5 star accessory = 1 5 star ranom accessory and if you want the guaranteed it would be like 15 accessory or something like this system, or make spider into daily change
