There is
3 different types for horseshoe. Its
Copper - Silver - Golden horseshoe
Their relation like; if i am opening a chest and get 5 copper horseshoe total, the next time when i open the chest and get the silver horseshoe; mine copper horseshoe
will be dissapear. Some goes for the golden aswell.
We can
gain them
from chest, caskets, special chest, precious caskets etc. Also
we can exchange things for golden horseshoe. For example,
Warrior weapons certificate for 3 golden horseshoe.
Its not a myth imo. They used to for
increase of luck to get
superior prize. When you get superprize the horseshoes you have will dissapear.
also you can use them
for upgrade your mount like cerrador 10 level to 13 level.
