 •Equipped items will now take "wear-and-tear" durability damage at half the previous rate
 •Please note that durability loss as the result of normal combat is different from the 10% durability loss characters will incur when they die. Equipped items have always suffered durability loss while fighting, and we are simply slowing the rate at which the loss occurs.
